Sig Sauer P250 2SUM Review

P250 2Sum Pack

Many avid shooters have multiple pistols; one for home defense, one for concealed carry, and/or maybe another one they only really use at the range.  When making a pistol purchase, many gun owners (or potential gun owners), will justify the purchase of a new pistol for a specific role like the ones mentioned above.  I fall into this category as well; before purchasing a pistol I’ll usually say to myself, “this will be a great concealed carry weapon,” or “this will be a suitable range/home defense gun.”  Well, what if you could make one purchase to fulfill both roles?

Sig Sauer may have successfully provided an answer to that question by introducing the Sig Sauer P250 2SUM.  The P250 2SUM uses one fire control assembly that can be transferred to any pistol in the Sig Sauer P250 lineup.  The P250 2SUM package itself comes with a full size and sub compact frame with one fire control assembly; allowing the owner to switch between the two frame sizes to suit their handgun’s purpose.  I’ve had the Sig Sauer P250 2SUM for about a month now, and a couple of kits for caliber conversions—as an owner of multiple pistols for different purposes, I was curious about what the P250 2SUM had to offer, and I’m ready to tell readers if the package deal from Sig Sauer lives up to the hype.

Sig P250


Out of the box, a new P250 2SUM pack comes with a full-size and sub-compact frame both in a black polymer finish, one firing control assembly, a hard case, and a magazine for each frame.  The 2SUM is available in two flavors, 9mm or .40 S&W, and the firing control assembly can transfer into any P250 frame and slide assembly (.40, 9mm, .357 Sig, .and .45).  The fire control assemblies for all calibers have a double action only action type and they’re available in a short or medium pull length, both at a 6.5 lb. pull.

Each frame assembly of the P250 features SIGLITE night sights and the full size provides plenty of picatinny real estate for mounting a light or laser.  The full-size frame also has a pretty large trigger guard which makes operating the P250 full size easy with gloves on.  The magazine capacity differs from models; the .40 full sizes will hold 14 rounds and the sub-compact will hold 10, the 9mm full size tops off at 17 rounds with the sub compact holding 12.

The 2SUM’s pistol frames feature a nice, comfortable grip, which is also interchangeable.  It has a rough texture that’s reminiscent of grip tape that some people add to their Glocks.  I have fairly large hands and they were able to grip the full size quite comfortably; however on the subcompact, I run into the same personal annoyance that I run into with other subcompacts—my pinky hangs off the end of the grip.  I know for some this isn’t quite as bothersome; however, for me I’ve always had to get a magazine extension just so I have that contact with the grip.  I understand that the short grip is an aspect that makes it a subcompact, keeping the size small, but for me personally, I like having as much contact with a pistol as possible.

Quality wise, I was thoroughly impressed with the Sig Sauer P250.  The polymer’s durability seems consistent with the quality one would expect from Sig Sauer, and the slide’s finish is nice and seems pretty scratch resistant.  I was a little curious on how the fire control assembly would be, expecting it to be a little bit more beefy in some respects, considering it will be taken out and reinstalled many times over (since that is the whole P250 sales pitch).  The whole control assembly seems sturdy enough, but there is one reservation I have.  The spring on the trigger assembly can rub on the side of the frame during install and uninstall. The spring actually has some lateral movement and can get caught on the side of the frame during install.  Needless to say, I would show a bit of care when installing the fire control assembly as it could be easily damaged it if it’s handled with haste or carelessness—which could leave your pistol completely inoperable.

P250 Fire Control Assembly

When hearing about the Sig Sauer P250 2SUM’s sales pitch, about being able to quickly transfer from one frame to the next, and/or one caliber to the next, without tools or much effort, I was skeptical.  Was it really that easy?  Well that question can be answered with the upmost certainty; yes it is that easy.  After making sure and confirming the weapon is safe, it’s basically a 4 step process.  Again, making sure the weapon is safe, one needs to lock the slide back, then rotate the take down lever and release and remove the slide—just as you would with pretty much any Sig Sauer pistol.  After removing the slide the take down lever needs to be removed by simply rotating and pushing it out from the right hand side.  The only thing left is the fire control assembly, which comes out by simply pulling up towards the front of the assembly until it’s at an angle—after which, the hammer needs to be pulled back slightly and the assembly can be lifted out of the frame (pulling the hammer back releases tension on the trigger which can sometimes take a little finagling to get it out of the housing).  After that, you’re ready to reverse the process to install the fire control assembly in the desired P250 frame.   To tell you the truth, after a few practice disassembles, I’m almost positive it took me longer to write this paragraph than it would for me to completely break down and switch up frames on the Sig Sauer P250.

Field Strip P250


Well, since the Sig Sauer P250 2SUM pack is essential two pistols, and even more if you have extra caliber kits like the ones Sig Sauer sent us, I wanted to go out to the range and out to the desert a enough times to make sure I’ve shot enough to be confident with how I felt about the handgun(s).  We had the P250 2SUM in .40 S&W, and 9mm P250 kits with the full size frame and subcompact, we’ve put about 1000 rounds in each frame and caliber, and after it was all said and done, I had very little to complain about.

Out of the approximate 4000 rounds we’ve put through all the different frames and calibers of the Sig Sauer P250, we had a very small failure rate.  I counted a few stove pipes on the sub compact with the .40, mainly using Federal ammo and virtually no failures with the 9mm in both frames.  I never once experienced a failure to feed or failure to battery.  All rounds went down range as expected, which gives me the assurance that the P250, in any configuration, will function as needed when needed.

Each flavor of the P250’s accuracy was exceptional and consistent throughout the different frames.  Expectedly, the 9mm was a little easier to control and keep on target with rapid succession shots; however that’s contributable to the cartridge, and not the pistol.  While I was able to keep my groups around the typical 3” at 15 yards I normally shoot, there was a slight difference with accuracy between the .40 full size frame and the 9mm full size frame.  While both groups were tight, the .40 seemed to shoot a little lower (about an inch) than the 9mm would.  I had some friends who went shooting with me on my sessions confirm this, and we all agreed that the .40 full size did seem to shoot lower while using the exact same sight picture.  It should be noted that this can be easily corrected by purchasing a lower profile Sight that is available through Sig SauerSig offers a variety of different sight heights to suit shooter’s needs.

P250 Shooting

The trigger on the Sig P250 is simultaneously my favorite aspect of the handgun, and the one area of regret I feel about this particular P250 kit.  All P250s are available in two varieties of double action only triggers, a short pull and a medium pull trigger length.  The fire control assembly that was included with our P250 2SUM would have to be the medium pull length, although I would hesitate to call the pull length medium.  For me, and for others who shot with me, the pull was quite long.  It’s not negative towards the firearm, but rather an unexpected aspect—if I were to choose a P250, I would opt to get the trigger with the shorter pull.  Al though the pull on this P250 was a little longer than I would like, it’s probably one of the smoothest pulls I’ve experienced.  The Sig P250’s trigger is extremely smooth, with a nice clean break, which directly lends itself to the great accuracy we experienced when testing the Sig Sauer P250 2SUM.

My favorite attribute of the Sig Sauer P250 would have to be after the range, when it’s time to clean the weapon.  Being able to take the fire control assembly out and having just a slide and an empty frame and exposed fire control assembly makes all the parts easily accessible; making cleaning it an effortless chore.  With everything exposed, there’s almost no excuse to have your P250 fail due to lack of proper maintenance.  Though it doesn’t necessarily take me a lot of time to clean my pistols, I can honestly say the P250 takes about half the time with less effort to clean.

Sig P250


Overall I’m thoroughly impressed with the Sig P250 2SUM.  Being able to switch calibers, or frame sizes quickly and effortlessly is huge added bonus to the reliability and performance that the P250 offers.  If you think about how much a quality concealed carry gun combined with a full size home defense/duty/range handgun would cost, it’s not hard to imagine the figure going well beyond the $1,000 mark.  At an MSRP of $945, and even substantially cheaper online or in local gun shops, it’s a steal.  I could really see LEOs being attracted to the P250 2SUM.  Since most LEOs I know carry concealed when off duty, and having the same trigger for both an on duty and off duty handgun would serve well in regards to consistency.

I’ve heard some people complain that having to move the fire control assembly from one frame to the other is a drawback to the Sig Sauer P250 2SUM; they view it as a negative that you can’t have two functional pistols at the same time.  I personally disregard that perspective in its entirety—the transfer of the fire control assembly to one frame to the next is so easy it’s comical, and I don’t really see it as a practical need for shooters to go around running Akimbo, or for those who don’t play video games, firing two handguns at one time.

Most of us have multiple handguns, especially us who conceal carry.  Sig Sauer took notice, and developed a handgun that allows shooters to accomplish multiple roles with basically one package, all while maintaining the quality and performance you would expect from a company as reputable as Sig Sauer.  The only thing better than the P250 2SUM’s performance and versatility is its price.  It’s almost a buy one get one free special when comparing the Sig P250 2SUM’s price with buying two complete Sig Sauer pistols.  With modularity being the ongoing trend of firearms these days, and more and more people buying multiple guns for different purposes, Sig Sauer has successfully paralleled a solid handgun platform that suits multiple needs, with a deceiving price that masks the excellent quality and performance you’ll get out of the Sig P250 2SUM.
