I received three of these magazines today hoping that they would work well with my Tokyo Marui Glock 17. I usually never write reveiws unless something really impressess me. these have nice finish that matches the finish of the TM G17. the port where the gas is released into the blowback unit is a little smaller than on the stock tokyo marui magazine which i beleive causes more of the gas to go into the Blowback unit opposed to being wasted. these fit into the magwell better than the stock tokyo marui magazine does. they slide in smoothly and drop out with the push of the mag release. the stock tokyo marui magazine doesnt click in as smoothly as these do and it doesnt drop freely when the mag release is pushed. the gas effeicency is better out of these magazines by a SUBSTANTIAL amount than the stock TM mag. the slide still has just as hard of a kick with these magazines so the increased gas effeicency is not a matter of reduced gas release into the blowback unit. for those who want to know, the base plate between these magazines and the stock magazine is interchangeable so all of the aftermarket baseplates for Tokyo Marui magazines will work with these WE magazines. all three of these magazines also had a tight seal and no leaks. This is a VERY preliminary observations from short use so i will update this reveiw (if possible) after more use.
Pros in a Tokyo Marui Glock 17:
-better gas effeicency than stock magazine
-equal or greater blowback than stock magazine
-smooth insertionn into magwell
-crisp "click" into magwell
-drops free of magwell when mag release is pressed (stock one requires shaking or SLIGHT help to fall free from magwell)
-No leaks (quick observation, will update if anything changes)
-slide locks back perfectly with these magazines
-None! (As of initial observations, subject to change)
-Actually, these dont have real glock logos like the original TM magazine. So, for those of you who care for realism, i suppose this could be a con.
