I got to the range the other morning and had the place to my self and was able to do some initial testing on my two latest guns, my Glock 21SF and the Sig 238.
I started with the 238 as I was pretty sure what to expect from from a used Glock.
First the good news, it fed all the types of .380 ammunition that I keep on hand, Remington 102gr Golden Saber, Speer 90gr Gold Dot, Hornady Critical Defense, and both Remington UMC and Winchester FMJ all fed well.
Bad news is that I had two failures to extract the spent casing from the chamber. All in all I fired 50rds of Rem. UMC, about 25 rounds of the Winchester, 20rds of Gold Dots, 15 rounds of the Golden Saber, and only about 12 rounds of the Critical Defense. Also of note is that several casings were mangled up pretty good, I meant to take pictures of them, but didn't. I'll follow up with those later. As for the extraction, I think the extractor is just a little stiff, some more testing is definitely in order.
As far as accuracy is concerned, I'm pretty happy with the results from a hasty rested position (resting arms on the bench) and a 2.75" barrel.
That was the last four rounds of Gold Dots @ 50". Not too shabby given the size of the gun.
As for the Glock, it functioned fine as was to be expected, but right now I can't shoot it as accurately as I would like, some low and left but mostly just buckshot pattern. I really need to get used to that trigger type. My order from Comp-Tac came in and I'll be taking the G21SF to tomorrows IDPA match and see how it runs in more realistic environment than a 50' fixed target point.
