45 Super

I am toying w/ the idea of converting my 1991a1 to 45 super. Will my frame & slide hold up to the round...assuming the work is done properly?

Don't know, that's why I'm asking. Seriously, it'll almost double the amount of $$ I've put in the gun so far to convert to 45 super, so I just wanna make sure I'm reaching some point of diminishing returns.
Well, since the entire conversion from .45 ACP to .45 Super consists of a heavier recoil spring I don't see how it could be messed up. Maybe there is something I'm missing but it sounds like you are about to be ripped off big-time. Who is doing the work?

To elaborate: the .45 Super is identical to the .45 ACP in all external dimensions. The brass is just stronger so it can hold up to the increased pressure. Therefore, there is nothing to convert except for a stronger recoil setup. I mean, what the heck are they going to change? The external dimensions of the barrel are pretty much fixed by the 1911 design and the internal dimensions are the same either way.

I agree. A good friend converted a S/A .45 to .45 Super by installing a #28 recoil spring. He has shot it numerous times with no problems. At first he tried a #32 spring from Wolff but it was so stout he could hardly rack the slide. I really just enjoy shooting regular .45 ammo and have never had a desire to shoot hot rod ammo. But to each his own. I did fire his .45 Super a few rounds. I hope that this helps.
I've thought about that conversion myself. If you check Ace Custom's website, the conversion kit includes more than just a recoil spring... I really couldn't say how much of it is really required.

In any case, it seems like a Gov't. model in .45 Super would make a nice gun for wild boar and similar sized game. Thoughts?

IMHO Ace Custom's .45 Super "conversion" exists to soak people. And a 32lb spring strikes me as completely insane; for what it's worth I'd be more inclined to go with a 24lb spring and a good buffer on a FLGR.

If you want to pay for a conversion, pay to convert your 1911 to .460 Rowland; it is more powerful and more companies make ammo for it. That way you will know your conversion was at least necessary to shoot the caliber, since .460 Rowland doesn't chamber in a .45 ACP barrel.

Glad to hear this! I think I could afford a new recoil spring and buffer easier than a $200-$300 kit. I would assume this would result in a much more magnified "+P" type wear effect on the gun? Just thinking out load I guess, but it's always good to have access to experience

I've been thinking of a conversion to .45 super myself. From all I've read so far, all that is needed is a heavier recoil spring and heavier firing pin spring (which should be paired with the recoil spring anyway. I'd add a recoil buffer for extra protection and call it a day. As far as extra wear on your gun, how much are you really going to shoot those hot .45 super loads?? I'd guess for plinking you are going to just use .45 ACP ball, and only shoot occasionally with the super rounds.

TC out.
How much of an impact on regular 45 acp does the heavier recoil spring have? If I changed a 1911 to say a 28# spring would it still function just fine with regular ball?
My understanding from reading the gunrags is that it will function with all full power .45 acp loads, but may not function properly with target loads.

I've been wanting a gun poject for the long winter ahead. I can't bring myself to alter my carry 1991 but was considering a similar project with a lesser priced 1911 that I could build up to my likes.

Would a 10mm conversion be feasable, or should I stick to .45 super. I reload, so ammo availabilty isn't a question as long as I could find some reliable data. I wouldn't want to undertake a project that would cost more than $800 right now, so do you fellows think that I could do this inside this price range.

Would the refinished Colt guns in CDNN be a good candidate fo a project like this? And finally is there a barrel out there that will stand up better to the accellerated wear?
