I have a Sig P220 in .45 and I would like to know if my frame would work with the slide and barrel and mags of a 10mm P220 Legion? I would like the Legion longslide and caliber combination if possible. If this is possible, where might I get the Legion parts? Thank you. | ||

The Legion 10mm has a stainless steel frame. If your P220 .45 has an aluminum frame, I wouldn't consider it. I think 10mm would pound the hell out of an aluminum frame and lead to a cracked frame. You'd be better off by selling the .45 and buying the Legion 10mm. | |||

I just want to shoot 40s&w out of the 10mm. | |||

I'll bet you can buy a used P226 in .40 for less than P220 Legion 10mm slide with a custom .40S&W barrel to fit the 5" 10mm slide. | |||

I've had a 226 years ago and never liked the round grip. | |||

Don't do that either. You will see plenty of people say they do it without problem. But it's a matter of tolerances lining up right to get away with it. I know a guy who semi-KB'd two guns doing it. Bad things can happen fast. | |||

I know the 10mm slides are slightly larger on the outside (several thousandths), because of not fitting well in many P220 holsters. Don't know about the inside dimensions, though, where the slide would ride on the frame rails. Just about everything on the 10mm is beefed up. When in doubt, mumble | |||

I've exchanged parts on Berettas and 1911's and Hi Power's etc and thought maybe since it's a 220 Legion that it might have the same frame as my P220 and have interchangeable parts. And I have a friend who has a 10mm Colt Delta Elite and just shoots 40s&w out of it so I was hoping to make a 10mm longslide and shoot 40. | |||

It sounds like you would like to end up with a convertible 45/10 P220. So selling what you have and buying a Legion in 10MM Auto is not the answer for you. The frames are the same, that is not the issue. For this to work the locking inserts need to be the same as well. Though you could swap locking inserts when you change slides, it is just more work. While you could make this happen with an alloy framed P220, an alloy frame is not a good idea from the standpoints of firearm longevity and shooter safety Your friend (and all who do this) is causing the extractor to be what the 40 S&W is head spacing on. As you have already observed, this does work. Unfortunately this practice puts extra stress on the extractor and depending on the firearm's design, usually leads to early extractor failure. I am guessing that this is not a money saving issue since a Legion slide and barrel in 10MM Auto is going to be pricey. We also know that you do not like the feel of the SIG double stack pistols already availble in 40S&W (P224, P226 & P229) Is there a reason that you want to keep this as a SIG Firearm? The cost of the Legion slide w/barrel in 10MM Auto plus some magazines will be as much or possibly even more expensive than buying a pistol already chambered in 40S&W There are many single stack pistols chambered in the 40S&W cartridge that have been offered over the years. I admit that most of those choices are from S&W As another solution, you could acquire a slide that is intended for 10MM Auto (remember this might require a locking piece as well) and have one of the custom barrel makers create a 40S&W barrel for you. You still need new magazines for this pistol ------------------------------------------------------------------ NRA Benefactor . . . Certified Instructor . . .

I like the feel and look of my 220 and really like the longslide on the Legion but I don't care for rails and I like shooting 40 so I'm looking for a way around the rail. | |||

There is always a debate shooting 40 out of a 10mm. My FK BRNO endorses the practice and the barrel is marked for both. The problem is carbon build up in the headspace shooting .40 in a 10mm barrel. You have to clean it religiously to avoid a problem going back to 10mm. It it were me, I'd get Bar-Sto to make a proper .40 barrel for the P220 - I did. Regarding head spacing between the 40 and 10, it's true they both head space off the mouth of the case. IRL, the extractor holds the case against the breach face, head space be damned. As I say my FK BRNO and STI Perfect 10 mark the barrel for both. But never take advice from someone on the internet | |||
