I got mine today.
Hadn't had time to check email last night, so I got the Puralator notification this morning, and about 20 minutes later the guy was at my door. What a nice surprise!
I got one of the 3.8s... unfortunately mine's one of those with a dysfunctional grip safety (dunno if everyone's was like this or i was a victim of bad QC -- i'd be curious to hear, if anyone else wants to post on the subject). Anyway, I dug around the web this afternoon, apparently WE copied the flawed TM design right into their own offering.
Given that the 1911 grip safeties are brilliantly simple designs (airsoft and realsteel alike), I decided to just take out the pin from the hammer spring housing and see what's up with these Hi-Capas.
As a sidenote, while I was disassembling the gun I noticed how the quality of the parts and fitting was really nice. No shoddy fitting or roll pins wedged in so tight they need to be hammered out; everything fits together nicely, and is put together nicely. I was very impressed, especially for the price.
So after poking around for a few minutes, I realized that the grip safety did work when I was holding everything together with my finger.
I finally tracked the problem down to the design of the hammer spring housing itself; the base of the grip safety has a small tab which fits into a groove/space in the hammer spring housing, and this groove appears to be about 1mm (offhand guestimation) too shallow. The effect is that the grip safety cannot properly return to its proper "safe" position, being effectivly depressed by the housing.
Ergo, the grip safety "doesn't work" (same idea as if you'd put Hogue Handalls on your 1911).
I wanna hear back from you guys and see if I'm the only one who got a lemon grip safety or not, but worst case I think a small modification to the spring housing would solve the problem (which is presumably the same on the TM Hi-Capa).
