I've owned quite a few of the various .45 offerings, similar to a lot of the responders. Glock 30 that I briefly owned was my only Glock ever.

Hands down SIG P220, its actually the only .45ACP pistol I have now.

I'll chime in. Glock 30S. Not as chunky as the Glock 30. At one time this was the carry gun of the LAPD SIS Unit.

Conceals well in my TTGunleather Slim XC Holster. Equipped with Trijicon DI Night Sights and Hornady 220gr +P FlexLock.

I have 3 45's now.....a Sig P227 from Custom Shop, a FN545 and a Ruger 45 carbine and love all 3!

I have an Sig P227 Nitron Carry. 3.9 inch Bbl.
Now that I have 2 long 14 rounders that absolutely work. The gun runs as good as with the other 10 rounders. Night sights are still good.
SA trigger is 4#. Not a very popular gun after they were discontinued. People make an opinion of them without shooting one. How would they know?

I only have the 1 for now.
Magnum Research (Bul armory) 1911 "compact" 4.25" bull barrel, stainless accents.
I changed the grips to Hogue rubber with palm swell, These seem the best grip for me.

Glock 21SF Gen 3 or Glock 21 gen4. I’m going to send both slides for optic cut.

Can't go wrong with the classics.
