The more I learn the more I think a lot of people (and parts makers) are completely full of it.
As you know, I have a circa-1918 Model of 1911 that I actually shoot. I either shoot milspec ball or Federal Hydra-Shock, which is kinda-sorta the same as milspec ball except it's a hollow point.
I'd used some fancy junk in the past, mostly Wolff springs, and paid attention when someone who allegedly knew more than I did made recommendations.
This last one just put me over, though.
Some forum idiot said that ISMI springs are just the cat's ass and that I had to have one. Well, what the heck, springs are cheap, I'll try it out. I currently have a Colt recoil spring in my M1911, and when last I shot, my pistol ran like a champ! It didn't feel excessive either with the slide coming back or the slide moving forward. It felt... balanced. Previously with the Wolff recoil spring, it didn't.
So I get the ISMI spring today. I got the 16# spring because allegedly that's "standard".
Put it in, and it was noticeably heavier than the Colt spring!
Tried to take it off my recoil spring guide and it would Just Not Let Go. It's off now. It's also in the trash.
When I buy parts from Colt they just fit and they work. The latest was a new Colt barrel and barrel bushing. Fits like a GI barrel ought to and the accuracy is pretty darn good. If I had a rest to shoot from, I don't doubt it would shoot to WWI specifications. As a carry gun, it's plenty good!
It kind of pisses me off all of the "you gotta get this" and "you gotta do that" advice. As near as I can tell, maybe for some fancy race gun it's important but for a military-grade pistol, it's all a bunch of useless crap. But I see people repeating the same garbage over and over....
I did get some other parts from EGW that I think will be worth-while. I got their max-spec pin kit, and as near as I can tell they are max but not oversize, so they'll fit my M1911. I also got their hard sear and it came with a decent enough polish on it that it might work without fitting.
But I am seriously done with most of those forum idiots. I will be plenty happy to have my military-tight M1911 and know that it will work each and every time.
By the way, Gus, read the private message I sent you last month. :-)
