Is it for sure to have actually a Gen 4 top on a Gen 3 lower?Are there any issues and how is the Gen 3 and Gen 4 frame (frame only, not parts) different?

Reactions:Buckshot Barry

No. No for a G17gen4 upper onto a G17gen3 lower. The recoil spring area of the G17Gen4"s on slide is too huge for the Gen3"s frame.

*"s a pic reflecting the difference in short article #5.
Ok, for this reason the top (frame) I have is plainly a Gen 3, but the serial # (according to glock when I inquiry them) is a Gen 4?! The upper has been having actually serious malfunctions lately.
Feel free to begin from the beginning and also develop a perform of questions. Images can additionally help.What friend (VANESSA) is call an "upper" is unclear to those of us who have read & comment so far. "Upper" isn"t usually supplied in describing a semiauto handgun, but if who does use that terminology, climate I"d translate it together the on slide assembly. I think of the "frame" as the receiver or the lower section of the semiauto handgun.The initial question was answered. The comment in post #5 seem come be acquisition this thread in one entirely different direction, however they"re statements and also not questions. Feel complimentary to elaborate.

The OP walk not show up to have enough familiarity v Glocks to understand what even significant sub-assemblies room called. This could become a very frustrating thread for knowledgeable respondents.
