is there a big difference in the G27 vs the Gen4 G27?
The gen 3 stock grip is larger than the the gen4 version. When you change the blackstrap,on the gen 4 to the next biggest it feels more like gen3 then there is another larger back strap.
I've also heard the gen4 extractor is more reliable tha the gen3
Also has a different guide rod and spring.
