If it won’t work for x macro, is there one from dpm that will?

Expert Answer

Answered by Ethan, Gear Expert, from IL, United States, on October 25, 2022

The DPM Upgraded Recoil Spring for the P365XL (MPN:MS-SI/26) will be compatible with the X-Macro as both the X-Macro and P365XL use the same exact recoil system (Guide rod, spring etc).

Q
RobertInTX, member, from TX, United States, asked on August 23, 2021

For shooting 115 or 124 grain FMJ or JHP, what combination of spring and spring plug has anyone found the best for a master grip type presentation?

Expert Answer
A
Answered by Tom B, Gear Expert, from IL, United States, on October 27, 2021

The best spring/plug combination will depend on your setup. 115gr ball ammo will shoot very differently that 124's. Also defense ammo will run much hotter. You will find your best setup with a bit of experimentation. A good starting point is the mid-range and either work up or down from there.
