I find that the Mantis is excellent for triggering feedback in dryfire. It very quickly and obviously displays a "score" which is a measure of how much you deflected the POA. 95 or better (the "Great shot" indicator) tells me I'm ok. It can take quite a bit of concentration to ke...

I'm working on adding international pistol courses to my BullseyeMatch app, but it will take some time. Google has significantly tightened the requirements for both authors and apps in the Play Store recently, and many may not find the hoops are worth jumping through. The minimum API ratchets forwar...

In my experience, the OEM buffer material deteriorates over time. This leads to cracking, and that means the recoil tube penetrates it and bottoms out on the retaining block. The longer distance then causes the recoil tube retainer to contact the end of the slot, and it bangs them both up. Net resul...

I was wondering what that silver piece was! Clever.

I'm with you on the buffer condition not making a huge difference, but only the solid Larry's ones. The OEM rubber bumper type is another story entirely.

I was thinking to use it for your tip-up nose height measurement, and being able to exercise the follower in-place to restack rounds seemed logical. Definitely not wanting to make a follower zip-gun! :)

It's all good, thanks.

Question (which is by no means criticism!) My printer-equipped friend printed the Thingiverse bench block and I discover it is oriented such that the follower button is beneath the magazine, so it can't be reached when the mag is in it. It's flipped relative to the red height gauge version in your p...

If you decide you absolutely MUST bend them, you'll want to try to anneal them a bit first. They're definitely hardened, you can tell by the DING! they make when you remove the parts. The most I'd do, personally, is squeeze the sides of the body gently to square them up, using a good vise or parall...

Good data. I'll check the follower condition on the two mags that responded to the flip.

...Other than when they've gotten pretty dirty, I've never had any issues with the 8 or so magazines I have for my two personal pistols. Based on all of the springs I've seen, I don't think the details are all that critical IF you don't have other issues (like the sharp chamber edges). Yup, totally...

Nice videos, very comprehensive! And the thingiverse jig is going to come in handy. One comment on the spring orientation. I agree that the free end at the top is oriented to the front from the factory, but I've discovered the magazine actually feeds a little better when it's placed to the rear . I ...

That makes good sense, I'll inspect some boxes/batches of my ammo, thanks.

Agreed on the Rimfire Blend, it lifts the lead beautifully and seems to prevent it from returning. Here's the same chamber view, post-cleaning.

It's time to clean my .22LR Benelli MP90S which has been keyholing and ejecting inconsistently. I took a look with my borescope before starting and there are some lead flakes and sootiness, which I expect. But I also noticed something odd in the forcing cone area of the chamber - tiny orange flecks ...

I do enjoy your app, and thanks for making it, and making it free! It didn't occur to me to reach out to you. Let me find a script/commands with the various times and send it to you via email. I looked over the 2018 ISSF pistol training manual and identified the following minimal required calls. I ...

So, I'm the author of BullseyeMatch and I've had this request in the past. Trouble is, I don't shoot ISSF, so I don't know what's important to implement. Plus, it's a lot of work to get these right, and shooters are tough to please. Oh, and my app is free (you're welcome :) . Can you be more specifi...

Thanks for the comparison pics. Mine (SN starting with 115...) most closely resembles the first, "beveled", and the rim is even all-around with no ramp or obvious relief. I shoot SK Pistol Match almost exclusively in it. Before the polishing work, rounds would frequently shave lead or jam ...

... In 2009, they changed the chamber design to include a significant radius. I've never seen one, but I suspect they basically added a bit of a feed ramp to the lower edge of the chamber. My MP90S was bought in 2016 (date code = "CP" same year), it had very little radius and no visible r...

If the pin doesn't stick out too much, the bevel on the tip usually takes care of pushing the pin back into the bolt. I don't know that I have ever seen a pistol misbehave due to dirt build up in the firing pin channel, but it's certainly possible. In my case, the rounds failed to chamber properly,...

Firing pin protrusion is definitely a problem! In my experience, it generally prevents the rising round from seating in the "pocket" at the front of the bolt. The rim bumps into the pin and everything goes haywire. This has happened to me if I let stuff build up in the firing pin channel, ...
