Chris, yes, this modular frame fits all but the 45ACP Sig P250 Compact. Convert your modular SIG P320 or P250 to a SubCompact with this Original Equipment Manufacturer Grip Module from SIG Sauer. This sub compact frame features a small grip profile that fits most shooters very well. Simply drop your existing P320/P250 fire control group into your new Grip Module and you have a whole new gun to suit a whole new set of parameters or circumstances.

As everyone stated, it will fit all but 45 ACP models. If you P250 is one of the original versions, the slide release on your gun is not compatible with this frame. However, the good news is, Sig was shipping the newer version slide release with the new frames and it is very easy to swap it out. I found this out the hard way when I sent my P320 frame in for a Cerakote paint job and was going to use my P250 frame while waiting for it to be done. Unfortunately my P320 had the newer frame/slide release while my P250 had the old style slide release. Anyway, it is a very easy swap and most people can do it without using a gunsmith.

Yes as long as your gun is NOT a 45ACP it Fits: SIG Sauer P320 or P250 Fire Control Group. 9mm, .40 S&W or .357 SIG Does Not Fit .45 ACP
