IPSC_RUS Posted March 21, 2011 Share Posted March 21, 2011 (edited) Hello, we have 3 G17s with a CCF slides and IGB match barrels in our shooting club. One gun with less than a 6000 rounds mileage had a slide failure. Another one with 4500-5000 have small cracks around striker hole. Guess it won't live as long as 300-500 rounds. Third one has 3000 rounds mileage and seems ok. Guess we will see somth intresting for the next 3000 rounds. The slide itself is very soft - deforms quickly in slide stop area. Question is: did anybody see anything like it? May be it's somehow related with use of Barnaul ammo? Edited March 21, 2011 by IPSC_RUS Link to comment Share on other sites More sharing options...
IPSC_RUS Posted March 21, 2011 Author Share Posted March 21, 2011 gun number 2 note small cracks on 11,1 and 5 o'clock Link to comment Share on other sites More sharing options...
BlueOvalBruin Posted March 21, 2011 Share Posted March 21, 2011 Wow, I haven’t seen anything like that. Most aftermarket slides I’ve seen are Caspian and Lone Wolf and I haven’t heard of firing pin hole cracking from either. Usually the problem is an offset pin hole or undersized striker channel in caspians. Any stock or aftermarket slide should be able to handle that ammo, afterall there are a lot of folks running 9 Major and .40/.357 sig full power defensive loads through their small frame glocks without these issues.

IPSC_RUS Posted March 21, 2011 Author Share Posted March 21, 2011 Despite my area of living (we are not allowed to have pistols or revolvers,only store it in Shooting club), I do work with Glock pistols for about 4 years. Those slides would score 3 points out of 5, meaning stock ones are 5 out of 5. Cheap paint, soft metal, Dawson and Heinie rear sight posts are sliding right and left if not glued. Main question is - maybe problem lays in cheap ammo? I saw Sigs with broken extractors on 6K-10K mileage. My mate's CZ SP-01 Shadow slide got cracked on 20K, another one lived for a 25K. All pistols are running on Barnaul ammo exclusively, sometimes getting Wolf's. Does anybody have any theories on the topic? Link to comment Share on other sites More sharing options...
usmc1974 Posted March 22, 2011 Share Posted March 22, 2011 Barnaul ammo is steel cased is it not? steel slaming into steel, seems like it would be hard on the slide. IMHP. Link to comment Share on other sites More sharing options...
Duane Thomas Posted March 22, 2011 Share Posted March 22, 2011 Not really. The mild steel used in steel cased ammunition is a lot softer than ordnance quality steel. In fact the nickeled casings that we put into our guns without a second thought are harder than the mild steel casings. In any event, a casing doesn't explain things like peened slide stop notches, cracked firing pin holes and whatnot. Obviously the culprit is inferior steel and/or heat treating.

EkuJustice Posted March 22, 2011 Share Posted March 22, 2011 I had a similar problem with the caspian splitting at the Striker hole. Tried a lone wolf no problem Link to comment Share on other sites More sharing options...
Lukenukem Posted March 24, 2011 Share Posted March 24, 2011 What kind of striker is being used? Link to comment Share on other sites More sharing options...
