On Building Light Weight 4.3 1911

[Wingman]

Looking to build a lighter weight 4.3 1911 but also want it to be able to use green gas. My plan is to use a Tokyo Marui MEU frame, a Guarder OPS Tactical .45 slide, a Tokyo Marui 4.3 outer barrel and maybe a Maple Leaf hop-up chamber and barrel.

Would a steady diet of green gas have any adverse effects on the plastic frame?

The frame doesn't care what gas you put in it. Green gas is what I've been feeding my TM 1911 for years now and there's no sign of any damage except for where I've dropped it (and even that's just scratches on the outside)

I was concerned that the metal slide slamming back on the metal inner frame might stress the plastic frame as the 1911 plastic frame is not that thick.

I like the balance of it (going to be using the standard TM 4.3 hop-up chamber now but the Maple Leaf stuff is on the way). I'm generally using full metal 1911's (KWC and KJW's) or larger plastic frame/metal slide pistols like ASG P09's or Glocks. They are really good pistols, but I like the compact feel of the 4.3 1911. 

I keep waiting for a Colt Combat Commander "top end" to come out.

Light weight and metal slide seems a bit counter intuitive ngl

Green Gas/Propane and Plastic Slide do not a good combo make (at least for me).. I blew up a ASG P07 w/plastic slide using Green Gas last year and a KWA M9 and SP2022 several years back. Wrecked a TM G26 Advance as well (ticked off about that one as it was one of my all time favorites. The frame now carries a HFC G17 slide and barrel combo and actually works super. Looks weird but ...).

4.3 will take green gas just fine, maybe throw in a recoil buffer for good measure. It's the 5.1 with the heavy *albatross* bo-mar sight that likes to break (because of how heavy the sight is).

Good to know. Thanks

Let me correct my original post:

I also have a TM hicappa that's been through a couple thousand rounds on green and it's stock except for the magazine gas routs.

IMO, buy a TM brand TM 1911 or hicappa, and use green.... and... that's it, enjoy.

^this

even metal slides break to the very same reason if they see some high volume usage

Whats a good threaded outer for the 4.3? Cheers!

[Wingman]

I have one from WE and it is actually pretty decent. It uses the same thread adapter that comes with many of their other pistols. Finish is very good on mine.

Rainbow 8 used to carry some as well.
