Got my advantage arms slide in the mail a few days ago and got it to the range today, thought I post a quick review and range report.
To start, the fit and finish is very good. The machining on the barrel is smooth enough for my tastes on a .22 and there aren't any imperfections or slop to speak of. It's a lot lighter than the standard Glock slide which I'd guess it has to be or else a .22lr wouldn't have a chance of cycling the action.
I tried three kinds of .22 at the range today. Shot 100 cci minimag HP, 50 Remington golden bullet round nose, and 10 American eagle HP. The kit specifically says that HP rounds won't be as reliable as round nose, specifically referring to minimags. Recommended ammo are minimag round nose, golden bullet, and cci ar tactical. Of the 160 rounds I fed it, I had about 6 stoppages. 1 was a fail to feed with the cci, 1 fail to feed with the golden bullet, and the rest were with American eagle. All things considered I was very satisfied with its performance. I didn't expect much from the ae anyway because it sucks, and it was pretty reliable with decent ammo.
Any fault in accuracy was due to my less than stellar pistol skills. Slow fire shots were all in the black and rapid fire all stayed in the outer most ring of the pistol target I was using at a distance of about 10 yards. As an aside, the stoppage I had with the cci was during a mag dump, pulling the trigger as fast as I could. Not sure if that could have contributed to the failure.
Over all id give it a 9/10. One point lost for stoppages, but it's a .22 so I won't cry over it much. Only came with one mag too, but they can be had for about 15-20$ so I'll grab a bunch more for cheap. Perfect option to practice with your Glock, take a newb to the range, or give to an inexperienced shooter as a self defense option. Hope that last one doesn't ruffle any feathers!
Ill probably update this once more when I run a couple more varieties of ammo through, or if, god forbid, I have any major issues.
