Hey everyone new to the forum recently went to the range with my 229 ran flawlessly took it home for a good cleaning when I couldn’t get the slide off only after market part is a DPM recoil reduction system that’s been installed for over a year with no issues I wiggled the recoil guide rod then I can take it down any insight on this subject thanks ?

Welcome Mack.

Just put the std. guide rod and spring back in it like it was designed for.

Yep, if the recoil assembly is aftermarket, and after you wiggled it you were able to successfully take the gun down, that's your problem. To verify, put the factory recoil spring assembly back in the gun and see if the problem persists. Pretty safe bet it won't.

Welcome Mack88

I have some Elite model Sigs that have the "Short Reset Trigger" and the slide does not just slide off without sticking unless I follow Appendix C. My pistols have factory rods and recoil springs.

Some food for thought...

After I completely read through the Sig Operators Manual, I found the following to be significant to some of the Elite series pistols I own that have the "Short Reset Trigger".

8.1 Pistol Disassembly
1. Unload the pistol (see section 6.0 “Unloading the Pistol”).
2. Retract the slide to the stop and lock open by engaging the slide catch lever.
3. Verify visually and physically that there is no round in the chamber.
4. Rotate the takedown lever clockwise to a vertical (6 o’clock) position.
Note: Steps 5 and 6 below are not applicable to SRT (Short Reset Trigger) models.
See Appendix C.
5. Retract the slide slightly to disengage the slide catch lever. Allow the slide to
move forward in a controlled fashion.
W WARNING – DISASSEMBLY
Slide is under spring tension. Maintain positive control during slide removal to
prevent damage or injury. Wear eye protection.
6. Move the complete slide assembly (slide, barrel, recoil spring and guide) forward and off the frame.

Appendix C: SRT Supplemental Instructions
Thank you for purchasing our new Elite Series pistol with Short Reset Trigger (SRT)
System. Please be advised that there is an additional step in field stripping your
pistol equipped with an SRT system. Disregard procedure 8.1, steps 5 and 6 and
follow the steps listed below:
• Pull back the slide slightly to disengage the slide catch lever. Hold the slide
firmly and allow it to move forward slowly.
• As the slide reaches its closed position, decock the pistol. This will allow the
SRT safety lever to completely retract so the slide can be fully removed from the
frame.
• Now slip the complete assembly (comprised of slide, barrel, recoil spring and
guide rod) forward and off the frame.
Should you need any further support in disassembling your SRT equipped pistol,
please call our Customer Service Department at (603) 610-3000 ext 3.
