Ive had my G27 for about a month now, I've ran about 700 rounds through it so far with zero problems with its operation. There are a few little quirks though that I was hoping you guys could help me with. First, when I fill my mags with 9 rounds, none of them seem to want to fit properly. When I do finally get the mags in all the way and hear the "click"...the mag release is so hard to push, it sometime takes both thumbs to push it and release the mag. After shooting my gun at the range and emptying the first mag, the rest of them go in so smooth it can almost be achieved by gravity alone. Second quirk, and I hope I explain this properly. The end of the spring on my RSA, the end that points to the exit of the barrel...seems to be working its way out and around the end of the black plastic piece. Has anyone seen this problem? Third and final issue I guess would be, the brass build up that has started on the feed ramp. I clean my gun regularly (after every range day) with Ballistol, I hear this is the best stuff to dissolve soft metals. I'm still unable to stop the build-up...any ideas?
All of those things are normal. I load my Glock magazines one round under capacity because it's easier to seat the magazine that way. 1. The magazine spring gets weaker while it's in use, so it's easier to load rounds into it. 2. The spring coming around the plastic muzzle cap on the guide rod is normal. I've had it happen with two G27 factory guide rods now, the spring won't come off, it just makes it a little bit of a pain to put the guide rod back into the slide. 3. The copper/brass on the feed ramp happens when the softer brass casing or copper bullet jacket rubs against the hard steel of the barrel as a round is chambered. You'll also see the same thing on the little rail on the bottom of the slide. What I find works best to clean it off is a phosphor bronze brush with Hoppe's #9 bore solvent. After using the phosphor bronze brush, I use a nylon brush because the bronze will embed itself in the steel as well but it's much softer and easier to remove than copper or brass. Then I dry the steel surface, wipe it with Ballistol oil for corrosion protection, then wipe dry.
Thanks for the reply, voyager4520. I'm glad to hear that I'm not the only one who has encountered the first two problems...and I'll do just as you said, to clean the feed ramp...I thought Ballistol would be enough...I'll tackle it from every angle now. Thanks again!
I have the same issue with the mags on my 27... Load your mags up and leave them full till the next time you shoot or for a week or so at least and it will help. My mags are still really tight since doing this but not like right at first I'm sure it does help a little at breaking them in. Good luck
