Well I headed off to the range this weekend with my G19 and I will cut to the chase... I have not been as lucky as many others here. I already did the long winded version of the range report here so anyone who wishes to read the extra stuff can if they wish. The short version is: Friday I went with 50 rounds of Blazer Brass 115gr FMJ, 100 rounds Magtech 115gr FMJ, 200 Rounds of Winchester USA 115gr FMJ, and 50 rounds of Winchester USA 147gr FMJ. Actually it was 204 rounds of the 115gr Winchesters because each box had exactly 102 in it, BONUS! Mind you this is my first Glock. My first plastic framed pistol at all for that matter. I shot some other handguns to compare the recoil with the Glock. I burned up 10 rounds of the Winchester 147gr's here(I only have 10rnd mags, I'm in NY) in my Ruger P89 and 10 in the Glock. All functioned fine. Then it was off to the weaker ammo. The 50 Blazers (PF=131.68) all fed and ejected and had no stoppages. However a large number of them went over my head, on my head, in my face or down my shirt. I didn't care for that BUT they did work. The 100 Magtech's not so much. Even more of those came right back at me and they felt a little weaker. Then the inevitable happened... A round didn't make it out of the gun: Rather disappointing but not totally unexpected. Although one of the reasons I had chosen the Glock was because of it's supposed "Battle Ready Out Of The Box" reputation. Yeah, not so much with the Gen 4's it seems. Anyway that was weak ammo (PF=130.53) so we'll let that pass. Onto the white box 115gr Winchesters. Noticeably more powerful (PF=136.85) far fewer of these came back at me. Unfortunately the ones that did confirmed the rounds had more power because they hit me harder. Not a single feed issue in the whole 200 rounds. I am thinking I need to stick to a Power Factor of 135 or greater though for the time being with this thing. I still had 30 rounds of the 147gr JHP Winchesters left though. They have a Power Factor of 145.53. I kept them for a reason. I wanted to test the Streamlight TLR-1 with Remote Switch I had bought for the pistol. So I loaded up the 30 rounds into my remaining 3 mags. Mounted the light and started the test run. First I have to say I don't care for the trigger part feeling on the grip, it changes how I hold the gun on a grip that I already feel is just a tad smaller than I'd like. That aside I set about to shooting it with the light on. The whole thing feels different. I had two feed failure in the three mags. One stovepipe in the ejection port with the next round half chambered below it and the other was the last round in the mag kinda stuck on the feed lips. Pretty disappointing I have to say because being able to mount a light was a primary requirement in the new pistol I bought. It would only wear the light when pulling house defense duty, I won't carry it with the light but it needs to function with the light. That being said there were some fit issues with the light that I go over in the long winded portion linked to above. The short version of that this picture should describe. Here the light is not screwed down tight but the remote switch it fully tight as it will go up against the trigger guard. It's obvious to see that it doesn't naturally fit on the rail straight; You can force it and tighten down the screw but this has the obvious natural side effect of pushing up on the front of the frame. Which is weaker in a Gen 4 than a Gen 3 because they had to remove material to fit the larger spring assy. So since I didn't like the feel of the switch anyway I decided Saturday to make a return trip. I couldn't afford that much ammo but I did have another box of 50 Winchester 147gr's and I picked up a box of 20 Speer Gold Dot 124gr (PF=142.60) and a box of 50 Speer Lawman 124gr (PF=135.16). Supposedly Speer say the equal sized Lawman and Gold Dots shoot and feel the same. Their PF numbers would seem to disagree with that but indeed they did feel similar to me. All shooting Saturday was done with the light without the remote switch attached. I much prefer the feel of the grip that way and it's the same when I practice all the time which I feel is important. So the remote switch is likely to stay off. So I started with the Winchesters since they were the ones that had two issues in three mags the day before. I put two mags through the tube of the Winchester 147gr's. Not a single problem. However the last round on the third mag did exactly what it did before. Looked to hang up on the bottom of the feed ramp. It didnt' look set back (nor was the one yesterday) so I just pulled the slide back and let it go and the round chambered fine. Mags four and five went fine. The failure though was the exact same as the second one yesterday so that might rule out the remote switch as the cause. Now I only had 20 rounds of Gold Dots. I chose Gold Dots because I have used them for years in my other pistols including my 1911 and have never had an issue with them feeding or functioning. So like they say go with what you know. Unfortunately I couldn't afford enough of them to make any realistic test that would matter. I needed to keep at least one mags worth for home. Thus why I got the Lawman. So... I shot the box of 124gr Lawmans and 10 of the 124gr Gold Dots. Not a single failure of any kind. However one mag of Gold Dots does not a test make. Four out of Five of the Winchester mags went without a hitch as well. I did note the 124gr stuff didn't come back and hit me in the face nearly as much, if at all. I rather liked that feature. However if it's the hollow point profile that's causing the occasional issue the Lawman aren't going to be a valid test. I need to suck it up and buy more Gold Dots. It may be a while before I can afford enough of them to so a comparative test to the Winchesters. So I have to admit I like how the gun disassembles for cleaning, I like how it feels to shoot, I like basically everythign about it except that right now I would not be able to consider it a reliable firearm. Right now my cheap Ruger P-89 is the only pistol in the house that has never has a single cycling/feed/eject issue of any kind. Not from day one out of the box. It's fired all the weak stuff this one doesn't seem to like as well. So I have to say, I am a little disappointed in the Glock I have to admit. I hope it improves but in the last two days I have put exactly 504 rounds through it with 4 failures. That's just not acceptable.
