Just got an SP5. Doing some research I saw that some folks like to shoot a few hundred rounds of +P ammo to break it in. Any problems with new guns jamming on lighter ammo. I have some IMI +P and some Fiochi +P+.

These guns needs full pressure ammo - Remington, Blazer, WWB are all well known to have issues in MP5 type guns.

I would do a couple hundred rounds of 124 grain ammo, preferably NATO spec. After it breaks in, it's going to be a lot more amenable to 115 grain range ammo.

I know I have fired a couple mags of JHP just because it was in the bag with me when I was at the range, but outside of that my SP5 has had nothing but Blazer Brass 115. Zero issues.

First magazine was Sellier and Beloit 115 gr. Then a mag of +P Samson. Then 5 rounds of Speer Gold Dot 124 HP's. Ran flawlessly with all. How often should it be cleaned? Every range trip? Sometimes I will only run 1 or 2 mags through my guns a trip.

When I got mine I used my plinking loads.

124gr w/ 3.9gr Titegroup.

I have 1000s of rounds through it without any issues.

Mine is pretty dirty from shooting it suppressed. It doesn't seem to care
