Default How reliable are 80% pistol frame lowers?

Hey Guys,

I was wondering how reliable the various 80% pistol frame lowers are. Are they on par with a factory sig or glock? Will they last just as long or not?

Thanks!

Depending on the tolerance used and how you fit the parts, quality of the parts. Can be very good.

One must be sacrificed to a dog. If the dog will not chew an 80% glock or sig frame but will chew the original, you know there is something wrong with the 80%.

The polymer80V2 is solid. The v1 had polymer rails you had to make by milling it evenly on both sides. You can imagine how that would either cause tolerance issues and/or eventual failure from wear and tear.

The v2 did away with it by making you remove the extra plastic sections as part of the process and install metal inserts.

You can build a g19 kit around $500 and a g17 at around $450 ish.

Keep in mind, building one isn't about saving money.

I've heard some horror stories from 80% builds. Some fly-by-nighters looking to make a quick buck.

P80 frames are good to go. I haven't put enough rounds through the 17, nor have I been able to take it anywhere in which allows me to rapid fire. For 1 shot per second intervals, it hasn't had any FTE or chamber a new round. No visible wear and tear on the frame. The rails are solid. V2 on the 17 is a must!!!

As for the 19 (it could just be mine), the railblock went on smoother compared to the 17.

When doing this project, keep in mind. It's easier to subtract than it is to add. Nippers and a dremel will help speed up the process.

You get what you put in, which is obvious. My 80 have functioned flawlessly. Some may be ammo sensitive. My 9mm 1911 Commander came together quite smoothly but I took the time to measure and filed and polished. P80 Compact cycled better than the Full in 40SW. When I switched to 9mm, no issues on either. The 40 conversion preferred full power or factory, no low power/timid reloaded rounds.
