Best frame for 10mm auto?

[Zedrek]

STI "Perfect 10" 2011 (any 2011 can probably be converted)
Wilson, Nighthawk, Dan Wesson, Fusion, Kimber, Colt etc 1911's
S&W 1006, 1066, 1076
S&W 610 Series Revolvers
Glock 20 & 29
EAA Witness

I'm sure I missed a few, but I'm pretty happy with that lineup. There could always be more I guess.

Colt Double Eagle Mk II Series 90
Wyoming Arms Parker

I like shooting all three of my 10mm. I haven't tried the Glocks yet though. The Wyoming Arms Parker is pretty cheap if you can find it.

Side note on the Colt Delta (at least for my 80's delta gold cup).
The barrel is not full supported, so I do not shoot full loads thru mine.
I think the majority out there are ramped and fully supported, dunno what Colt was thinking.

good luck with choice.

I like the smaller framed 29SF but own the 20.

I love how the Glock 20 SF fits in my hands. Reliable and accurate. Price is right also.
