Congrats on the buy, you won't be disappointed!
When you get it there's one quick trick you may want to try out... Take off the grip frame (just two screws) then look at the front grove where it slides onto the mainbody. See how the forward trigger travel is stopped by the extrusion on the body? Well, shim it up! May I reccomend black electrical tape? It may take few trys to get it the length you want, or as short as it will go while still reliably re-cocking. It's a really simple and really quick mod. Have fun!
