Re: Generation 4 Glocks?
I spoke with my local smith about them. He said they've had four come back to the shop with broken guide rods. Last weekend I RO'd at a local GSSF match and asked the armorer about it. I was told that while he hadn't seen any of the failures personally he knew Glock was changing the GR's and they would be in by the end of the month.
I like the RTF texturing on the the grip. I'm still not sure how I like the new cocking serrations... I asked about the backstraps. They apparently call them "inserts" but IMO they sound more like panels. The backstrap panels are not like the M&P. They fit over the grip and are held in place by a pin. The Gen4 starts out as a short frame. You remove the pin (which is actually a G36 pin) and the med. insert brings the grip size up to about the size of a std. med. frame (17, 22, etc.). The large insert brings the dimensions to just under a large frame.
I'm sure they'll get the guide rod issue worked out but you won't be able to use earlier mags without modifying them due to the reversible mag release.
