Surprisingly comparable to the real thing in terms of feel and handling (aside from the short slide travel) even the trigger pull has that mushy and uneven take-up and no real sear wall before the striker fires off. There are no cut outs for red dots but the bottom rail does mount most lights although it's a bit tight. I personally use .43 cal rubber balls and have a little shooting range in the bush behind my house and its a lot of fun!

I purchased two Umarex T4E Glock 17 Gen 5 .43 Cal Paintball Markers in December. They are outstanding.

I disassembled them and used graphite lubricant on all the surfaces that rub together, and both guns operate super smooth, and very realistically.

It is, however, more difficult to remove the slide on this gun than on a real Glock. When removing the slide on this gun, it is really helpful to remove the front pin, which is pretty easy.

There are many types of .43 caliber rounds available, from Paintball, to Rubber (various types) , to Pepper Ball, to PVC, to Chalk, to Glow in the Dark, to Aluminum, to Steel, so I like the large variety.

The weight, feel, and premium build quality of the gun is very impressive, I really like it.

My only complaint, is the price, ouch.

Excellent look and feel. Better slide action on this than the S&w m&p9. Though I like the trigger feel on the S&w better. Great overall replica. Not for small hands! S&w will fit better!!
