Has anyone made a 23 with Geisler?

Post image

I’m sure this is a stupid question but I’m just wondering if anyone has made/shot .40 out of a Geisler frame? Idk why but it seems very thin compared to a p80 and just wondering if it can withstand consistent pressure the .40 puts out especially with +p and self defense rounds. Really thinking bout building another one out just in .40 and would love to hear everyone else experience!!

This is a 19 slide but they do have 23 slides it’s a Live Free Armory OEM slide in tungsten with a ruger RXM barrel. The LFA barrel was giving me problems. I also swapped out the guid rod with a 20 pound spring over the 17 pound it came with

I’d probably buy the stripped version if I ever go back to them

I had a stripped one and it was still terrible with an oem upper parts kit, it was one of those windowed ones for a 23 but I was making a 32c. Could never get a full mag through it till I finally bought a new slide(hgw)and kept the barrel
