I would have to choose the gun I know best; the one I know would survive dents, scratches, dirt and not a safe-queen; my first handgun that has been used over and over again for many years; the. Colt 45 Series 70!

Well I have the most rounds through my 229 in .40 so I would have to say that that would be my one and only if it had to be. Right now I am loving the 1911 platform and that could be a game changer in time.

For one that does it all I'd have to pick my P225-A1.

G19

Sig 226 Legion

1990s SIG P229.

Colt Python .357.

I carried a Glock model 23 in the line of duty and still carry one everyday. Kinetic energy of a 45 with the capacity nearing a 9 mm while still concealable.

My Wilson Combat CQB (full size).

My cut down G17, takes G19 mags, or my SW M29MG

I know you said one but I can't decide.

Another vote for the G19.

A gen 5 Glock 19

Glock 19 or 34

G20 Gen 3 SF because I like to hunt with mine and also for CCW.

I live in California- EDC is not a real option in most of this place.

IF EDC was an option, I might change my options.

However, I've thought about this a bunch, and have identified 5 options that I'd be ok with for this.

• 1911 in .45acp- with a Nelson .22lr conversion for range fun. Ideally, this would be one with a ramped barrel, so I could also mate the frame up with 9mm or .40S&W top ends. However, a simple .45acp frame would be ok with me. Probably want a CCO size, to allow EDC, but, again, I am in California- so I may as well just go 5"
  
  
• Glock G30SF, with 10mm barrel, and .22lr conversion kit. Easier to carry, more rounds, reliable. 'nuff said?
  
  
  
• Browning High Power in .40S&W, with a 9mm conversion barrel, and a .22lr conversion kit [ciener makes some]. Probably my favorite centerfire bottom feeder to shoot.
  
  
• Glock G23, with 9mm conversion barrel, .357sig conversion barrel, and .22lr conversion kit. This will do nicely- thank you. Unfortunately, .40 is my least favorite centerfire round.
  
  
• Ruger Blackhawk 5.5" .357mag/9mm conversion kit. Yes, SA revolver- yet it gives me .38Special, .357mag and 9mm for cheapest range play.

I would be hard pressed to select a SINGLE one of the above dream setups. But, I can dream, can't I?

Glock 20 Gen4 sounds like the best option for its mix of power, capacity, and simplicity, but I've never fired one.

Out of what I have shot? Think I'm gonna go with my H&K P2000. Ergonomic, good capacity, about the dimensions of a G19.

Other considerations would be SP2022 and FNX .45

P320, compact. Same size as the Glock 19, but a better trigger. I would swap the grip to a size large, sand the grip sides flat, and then stipple.

I trust my Gray Guns worked over P226, with both .357 and 9mm barrels, with my life. However the P320 is so easy to clean that is what I take to the range every time.

G19 Gen 4

Glock 19 gen 4 also.

I have a reasonable pool to choose from, but in terms of capacity, concealability, compact bang for the buck, I keep coming back the the Glock 19, especially since 9mm loadings have matured to the level they’ve reached.
