Want To Build A Uspsa Open Class Glock

[Glk21C]

I have a 20C that is modified for USPSA Limited class, using a .40S&W chambered barrel. The lower has been modified to a point that I don't want to fool with it, I like it just the way it is. I want to use this G20 lower and possibly build the upper out of parts that would enable me to compete in Open class. I was thinking the following:

6" long slide/ported

6" long barrel chambered in .40S&W/ported

some brand of red dot sight

Any information that anyone is willing to give on this is very much appreciated. I want to stick with the .40 S&W cartridge just for ease of reloading since I am already set-up for that shooting in Limited class. I also don't want to buy the G35 or G24 as I prefer the feel of the larger frame and I am pretty sure those have the small frame.

Thanks everyone

I would skip the longer slide. Go with a longer barrel and comp. I'd likely port the barrel.

BTW, I think 38 Super COMP will run just fine thru the 10mm mags. fwiw

im with flex on the comp and ports

no need for longslide

Used to be able to get 9x23 barrels for the G20 that worked with a little tweaking of a 10mm magazine. going to 9x23 will get a few extra rounds in the mags.
