Staccato P, SRO, stovepipes...

Any more info, like bullet weight, which recoil spring, number of rounds through the gun?

SRO does have a slight lip that most other red dots don't have. This occasionally causes issues with bouncing cases back into the action. This is the first I've heard of it happening on a Staccato but I would expect the SRO is the culprit.

Ammo was either Blazer Brass 115 or Sellier & Bellot.

(Don't remember SB weight, but probably also 115 — and just switched over to the case of BB, so it could have been either,

Haven't changed the spring so I assume it's the Medium.

It worked fine on Monday.

I disassembled, cleaned, and lubed the Staccato yesterday — it took a while to get it lined up correctly to reassemble, so maybe something's slightly off?

My thoughts are if it's low round count, it could just need broken in, or be weaker ammo. It's not significant, but the SRO is added weight. I would try some 124gr or 147gr and see if it still happens.

Good idea — I'll give that a try.

Maybe check your recoil spring too just to see what color/weight it is. Not sure if Staccato still includes the pack of extras or not.

I’ve seen quite a few people have “ejection issues” which actually have zero to do with the pistol.. most caused by their thumb(s) touching the slide in its movement, slowing it down ever so slightly

I agree, but the OP stated the issue didn't happen until he mounted the SRO. Not saying it couldn't have been happening before, but seems like he would have had issues without the optic too. It never hurts to have someone watch for you either, or another shooter.

Does the SRO over hang breech face? I'm not all that familiar with all the red dot dimensions but I've been told by my red dot friends that sometimes even small amounts of over hang can induce malfunctions with different loads.

touché! I clearly didn’t read very carefully..

I suppose I’ll still try to add something productive to the conversation. …

I don’t recall exactly if the right side threaded hole for the optic plate is a thru hole into the extractor bore… I think it is. But if you just added the PLATE AND SRO, make sure the screw isn’t too long and contacting the extractor.

I have no issues with my c2 or p with SROs.

Agreed, I have more than 10(kinda embarrassing haha) 2011s to include a few Ps and C2s that all have SROs and I haven’t had a single issue with the “overhang” granted YMMV, but I’d assume it’s something to do with springs or ammo before I’d think it was the optic itself.

Had stove pipe issues with my XC also with the SRO. My gunsmith got it running good tweaking the extractor but then it started stove piping every 200 rounds unless I oiled it. Finally just moved on from it.
From what I’ve been told these pistols should go well beyond 200 rounds without requiring oil.

Since it ran perfect with 124gr plus p, it still makes me think the recoil spring may be too heavy for 115gr. I think it at least rules out extractor issues.

I wonder if it's better to buy an iron sight model and have it milled so the SRO sits further back if it's your optic of choice? The optic thing is still very new to me. In doing research to have mine milled, it seems like there are plenty of different vendors that offer direct mount and plate options.

There are plenty of pictures out there with staccato's running SRO's and lots of reports of them running issue free. You'll get it worked out.

Thanks Snatch -- I'll try the lighter spring next time at the range.
