I recently acquired a used Glock 19 gen4 though a PPT and The guy I purchased it from had a gen 3 guide rod in it, any ideas as of why some one would do that?

Early on, some people thought the Gen 4 guide rods were problematic. Some companies made an aftermarket adapter to use the Gen 3 rod in Gen 4s.

I don't know what the problem was or if the newer ones don't have the problem. If it were me I'd buy a new Glock guide rod and try it.

That's what I want to do, try an OEM guide rod I was just checking to see if someone could shed some light on the subject. Is the gen 3 guide road better than the gen 4 ?

Eldub1950 covered the history aspect of the Gen 4 multi spring RSA (ancient history now). The other reason it is worth hanging onto that Gen 3 adapter and guide rod is it is easier to change recoil spring weights. In the end, get a new stock Gen 4 RSA and keep the Gen 3 unit with some extra light springs for fun and games at the range with light target loads.

Gen 4 rod is 'supposed' to help with recoil a little. I can't tell any difference but I'm not recoil sensitive. Always good to have a spare guide rod so a safe investment of 15-20 bucks. Not sure what that adapter looks like but don't lose it just in case :)

All my Gen 4 guns shoot softer to me than their Gen 3 counter parts, some quite a bit softer, I think the multi spring RSA is the reason.

Great, thanks for the info. Should I get aftermarket or OEM?

IMHO - unless you're tuning you gun for specific purposes, I'd go OEM. Especially since you recently bought it. Go OEM and make sure everything's working right. Then feel free to experiment. If you experiment with aftermarket parts first, and something isn't working right, you can't be sure if it's the part or the gun or you.

field strip the gun, throw the gen 3 part out, buy a gen 4 RSA.

Just FYI

Glock screwed up the RSA when they initially released the Gen 4.

Users were getting failure to feed, stovepipe, & brass to face. It took Glock a while to come out with a new and improved Gen 4 RSA. And in the mean time aftermarket had already figured out the problem to the Gen 4 malfunction and introduced the adapter for Gen 3 RSA to be used in the Gen 4.

OP, just buy the new RSA Gen 4 and you'll be fine.
