G29 QUESTION-Gen 4 spring in Gen 3??
 

I wen to my local dealer with the idea of getting a second G29 in which i would put in an extended barrel. He had 3 new ones-all Gen 3's on the outside, but the recoil spring was of the Gen 4 type (dual but with the key hold tube etc..)
all else was gen 3-grip, mag release etc..
Anyone else seen this?? I passed on it as i was worried about the function. Just wasn't sure if this hybrid set up would effect function.
Anyone have any thoughts or experience on this issue?
Thanks

This is my current setup. When I sent my 29sf into Glock for repair they replaced all the frame internals and swapped out my recoil spring for the new one. It runs 100%, and I swear it shoots softer with the upgraded recoil spring.

My G29SF sports the new style dual spring as well. I really prefer it, softer feel and it keeps the slide off the frame even with my hotter loads. Reason enough to get a Gen 4 G20...

Thanks for the info. I am going to pick one up tomorrow or friday.
