Hi guys. These TM guns will be bought as backups due to colder weather in my area of VA, the fact that H&K is awesome, and some of my squad's GBB's are OoC(out of commision) I've read many reviews, and just need a bit more info. The version that will be purchased is the High Grade Hop-Up version. UPDATE:My retailer was supposed to ship the gun today, but now I'm on back order. For a refund I have the option of the spring TM P7 and the spring M1911 government. Both are HGHU.
