Someone mentioned earlier in the thread that all Glocks are the same externally, i.e. a holster that fits one compact Glock, will fit all compact Glocks, subcompact to subcompact, etc. Not so. The high calibre Glocks, such as the G20 and G21 (10mm and .45, respectively) are physically larger pistols than their 9mm and .40S&W counterparts.

Really? I thought the barrels and mags made a difference only.

No, slightly larger dimensions are required for the larger 10mm/.45 rounds. While most (if not all) 9mm and .40S&W pistols are the same size, that was a result of the similar dimensions of the two rounds. However, the .40S&W is a much hotter load, and early .40s wore out the guns quicker, and it was several years before manufacturers produced pistols specifically designed to handle the higher pressure .40S&W loads.

I'll shut up now.

anybody know if the KSC G19 GBB Pistol (Metal Slide Version) has a metal outer barrel or just plastic? link: http://shop.ehobbyasia.com/ksc-g19-g...e-version.html

thanks.

why don't you just e-mail them to ask right away ? I would say it's metal since the pre-upgrade KSC Glock 19 is full metal that what I have seen.

today i received my ksc g19 with an extra mag. while filling gas in one of the mags i well heard the sound of gas flowing in the mag. however when filling gas in the secong mag i couldnt hear anything. both of the mags shot nicely until empty of gas (last shots were weak). when starting to refill the gas then one of the mags let the gas out as soon as i started filling. not as fast as pressing down the valve but about 3 seconds of refilled gas came out in about 6 seconds. whats going on- can i fix the mag? it is brandnew from ehoby asia and has had only one fill of gas.

did you add lube? if it's brand new there's a good chance that it was sitting for a while and the seals dried up.

I'd pull the main seal and give it a silly oil bath to rehydrate it.

there's also the possibility that one of the valves has failed. where exactly does the gas leak out of?

it leaks out from the top of the mag. i dont think it leaks from the valve. i can see the cloud of gas pushing out from the top but not from the side. is it possible to repair? could it be done with a new part?

regardless. if it's the top or side it's probably going to be the flow valve. write back to the vendor and see what they can do. at the least they could send you a replacement valve. well, that is if you actually get a reply.

ehobbyasia replied with this:

"Can you try to apply some silicone oil spray on the leaky valves.
Give the O-ring as good lube to try and help the seal"

I understand I should take the mag into pieces to get to the valves right?

yeah, you can try silly oil. put a drop or two down the hold on top. tip the mag on it's side and put a drop or two on the valve release (button). let it soak over night then pressure it up and see if you get the same results. if you have a valve tool, you can remove the flow valve itself and dunk it in some silly oil to swell up the rings a little.

i hope this is enough of a newbie question:

how important are the two springs (part 23) in the blowback chamber. i disassembled my gun today and to my horror i saw that the top parts of both of the springs were out of shape and very bent. it seems its impossible to bend them back straight. and i dont have a clue how or why they got so abused.

-edit-

seems i installed the blowback chamber incorrectly the previous time i disassembled the gun so that the springs were cought between metal and got abused. i managed to bend the springs almost straight. i think the problem is solved.
