'Stiff Magazine Spring'Of the two magazines that came with the unit, I had no problem loading on one with all 14 rounds (both had +2 magazine basepads). The other magazine, however, would only load up to 12 rounds, and no more. I figured something could be wrong internally in the magazine, so I disassembled it. I couldn't find anything wrong with it, though, so I re-assembled it again.
After re-assembly, there was a slight improvement in that the magazine would now load 13 rounds, but I had trouble loading the last round. I decided to just let the magazine stay loaded with 13 rounds for a couple of days, allow the spring to soften up a little, and maybe I would be able to load all 14 rounds later.
After two days, I tried to load the 14th round, but it still wouldn't go in. I finally disassembled the magazine, then separated all the parts individually. Again, couldn't find anything wrong, so I re-assembled the magazine, then tried loading the magazine again. The 14th round finally was able to fit into the magazine, but only after a lot of pushing and handling.
Left it again for a couple of days, then removed the rounds, and put them back in again. I was able to load the 14th round, though still with a bit of difficulty. I don't know what happened with this particular magazine, probably some tolerance or fit issues as the other magazine was working fine.
'Disassembly and Trigger'It turns out that all that was needed to be able to consistently and quickly disassemble the gun was a lot of practice. After disassembling/assembling the gun again and again, I can now do it on the first attempt. One thing good about disassembling/assembling the Glock, is that you do not have to take out/in any disassembly lever before you can slide out, like on the 1911 or my P250. Its so simple: Nothing to take out/in, no loose lever, just slide out, and then slide in. No doubt in my mind that this is the easiest gun to disassemble/assemble that I have tried out so far.
