Closest similar product is my real steel/composite Glock 37
Rap 4 w/Rap 17 as backup
Mine was great as-is
smallest marker I know of, 12 gram c02, realism, gas-efficient
Have to buy the tough rap4 paint or it will chop, not easy to disassemble
This is a truely great sidearm marker. A paintball pistol comes in real handy when your main marker only holds 21-round mags and has to be continually reloaded. I hold my RAP17 in one of the magazine holders in my vest, and it is just a second or 2 away from deployment if I either run out of ammo, am in a situation too tight to maneuver my main marker, or if my main marker malfunctions.
The Rap17EX itself holds a maximum of 10 rounds in a metal magazine that is loaded into the pistol grip much like a real pistol. 10 rounds fit awfully tight in the magazine, so I usually go with 9 rounds. The new mags are metal, and I have 3 figuring I will use no more that 30 rounds in any one game. The mags are very easy to reload, so if I do need more I just load them up again.
The marker fires .43 cal paint, which as far as I know can only be bought from Rap4.com. For the Rap17 I find that you need their heavy duty paint. It never breaks in the barrel, but the down side is that it may not break on your soft target. I can get about 50 shots from a 12 gram cartridge, which also fits in the grip next to the magazine. I can usually get a 1foot grouping from about 60 ft, which is sweet cosidering i am just pointing and shooting usually from a standing position.
The one thing to watch is that you put a drop of oil where the 12 gram sits on the rubber o-ring every day you use it, or you will be spewing c02 out the barrel of the marker. The velocity is easily adjusted on a screw behind the grip, but I always keep mine on the maximum. Also, I find that oiling the slide where it makes contact with the composite body of the gun will help you get more shots from a 12 gram without having to recock the thing after going through 3 mags of ammo.
If you have the money (279.00 new) get this backup marker! I got mine used and it still works great. It looks just like a real glock, and weighs about as much, if not a little more. It is great for tactical play and unparralleled for milsim action. Make sure you get the EX version with the 12 gram though. You will be impressed.
