DPM in Q5

DPM is certainly a good system and you will be happy with it. However I will suggest you look into SprinCo recoil systems. Alan makes a really great system that he has fine tuned for the Qs and if you need individual attention he will be happy to assist you...

Sprinco USA -- Recoil Reducers

I've used DPM but switched to SprinCo a few years ago and my EDC weapons all have Alan's systems.

Welcome to the Forums BTW...enjoy your time here.

^^^^ THIS.

I've tried both and neither offered an appreciable reduction in recoil. I have found using a non-fixed stainless steel guide rod and tuning the pistol to the load through varying spring rates to be much more effective for a competition gun. For a defensive weapon I personally prefer to use factory spring rates to ensure reliable feeding.

I have the Sprinco and it it shoots a lot softer.

I have been EDCing a Q since 2011 both personally and professionally. Because of an injury I must manipulate and fire my weapon one handed.

Due to one handed shooting I am a bit more sensitive to getting back on target quickly and having tight accurate groups. After careful consideration and testing I found Alan's SprinCo system to offer the very best results.

I have yet to have a failure with the exception of those deliberately manufactured for the purpose of proficiency training. In fact I trust my life and that of my family and comrades to SprinCos every time I carry my Qs or P99.
The only exception is carrying my Q45 because Alan hasn't quite fine tuned the RSA for that model yet.

I have tested both as well. With the Sprinco system (yellow spring), my Q5 "settles more quietly" in a split second, as compared to with a one piece rod and 13lb spring, if that makes sense. With the latter, my red dot moves and settles more violently (kind of wobbly for a lack of better term). I guess that it is because the slide hits the frame harder at the rear end??

I have decided to stick around with the Sprinco because of this difference. Recoil is still there while its impulse is softer.

For self defense, I would stick with the factory spring (my policy = no mod to SD guns).

Sprinco for gun games and factory for self defense here also.

Ciao ragazzi, ma quante libbre è la molla originale?

The original 'red' spring RSA in the Q5 was 48 Newton (10.79 lb). The silver spring is 50 N (11.24 lb).
