MantisX or SIRT — which one actually moves the needle on your dry work?

Question

I've used both over the last eighteen months. Here's the honest difference:

**MantisX** excels at isolating the trigger press and sight picture. Mount it, dry fire at your phone, get real-time feedback on wobble and reset. The data is useful if you log it — I track deviation by week in my notebook. It catches drift you won't feel. Cost is low. Limitation: it only sees what the camera sees. Hand position, grip stability, draw-stroke quality — invisible to the sensor.

**SIRT** is a training tool masquerading as a pistol. Same trigger press as live fire. Full draw-stroke practice. Recoil impulse is gone, but that's actually useful early — you isolate the press without fighting the gun. I've run it as a 1:1 substitute for live fire when I'm working a specific malfunction or draw sequence. The price reflects what it is.

**What I do:** MantisX for isolated dry reps on the trigger (20–30 min, three times a week). SIRT for full-cycle drills when I'm stress-testing a new draw or position. Both go in the notebook afterward — what worked, where the wobble lived, par times on the drill.

Neither one replaces deliberate practice. Both require you to know what you're practicing and why before you start.

What's driving your question — trigger work, or full-draw progression?

Let me break this apart, because there's an internet argument hiding in the weeds here.

**What are we actually measuring?**

m.delacroix ran live fire twice a week and isolated trigger work with MantisX, then treated the data as if one tool owned the gain. That's honest self-awareness about confounding variables—but it also means we're looking at a highlight reel, not controlled comparison. Ten weeks with concurrent live fire tells you "concurrent training works." It doesn't tell you MantisX was the limiting factor.

**Where the real gap lives:**

Both OP and m.delacroix are treating these as interchangeable for "trigger work," but that's not where SIRT actually wins. SIRT wins because you're running the *full draw-stroke cycle* under the same mechanical constraints as live fire—holster draw, presentation angle, grip establishment, trigger press sequence. You can't film that with a phone camera. MantisX can't see your holster clearance or hand position during presentation.

If you're working par times on *draw-to-first-shot from concealment*, MantisX gives you trigger wobble feedback. SIRT gives you the actual mechanical sequence that determines whether you clear the holster clean, whether your grip is established before you press, whether your sight picture recovery happens *during* the press or after. Those are different problems.

**My actual recommendation:**

Use SIRT if your training goal is draw-stroke repeatability or malfunction response under time pressure. Use MantisX if you're isolated on trigger press mechanics (low ready, already presented). Don't run MantisX for draw work and call it draw practice—you're missing half the drill.

gulfcoast_ops nailed the confounding variable piece—m.delacroix's honesty about concurrent live fire is refreshing, but yeah, that's two training inputs competing for credit.

Here's where I'd push on the framing though: SIRT isn't "better for draw work" in a vacuum. SIRT is right for draw-path work *if your bottleneck is mechanical repeatability under time pressure*. Wrong for it if you're still building grip fundamentals or testing different carry positions—because the gun weight, holster geometry, and concealment type all matter, and SIRT erases those variables.

I run SIRT for draw-to-first-shot from my AIWB carry setup specifically because I'm stress-testing the same grip angle, same trigger guard geometry, same presentation path I use live. That's worth the cost. But I've seen people use SIRT as a draw-work substitute when they're really just practicing trigger press with a holster attached—and that's a gap.

MantisX *for draw work* is what gulfcoast said: you're getting feedback on trigger wobble during presentation, not on whether your hand cleared the holster clean or your grip was established before the press. Useful data, wrong tool for the question.

Honest question back at you both: Are you running these as isolated diagnostics ("What's my trigger doing right now?") or as holistic draw reps? Because that choice flips which tool owns the session.

I ran a ten-week block with MantisX—trigger work only, same drill every session. Tracked split times on a five-shot string from low ready. Week one baseline was 1.8 seconds average to first shot. Week ten was 1.34 seconds. Deviation tightened from ±0.24 to ±0.09 across the five reps.

That's real. But here's the honest part: I was also shooting live fire twice a week. Can't isolate which tool owned that gain. MantisX gave me the feedback loop—I'd see the wobble, drill it, see it shrink. Whether that's 60% of the improvement or 20%, I don't know.

Where MantisX hits hard is when you're chasing specific issues. Trigger control under fatigue, reset speed, sight picture recovery. It'll show you the data. For par-time work on a known drill, it works.

But if you're stress-testing a draw stroke or practicing from concealment, you're guessing without the gun in your hand. That's the gap everyone should name upfront.

m.delacroix's par-time data is solid—I've run the same isolated trigger block with MantisX and logged it the same way. Ten weeks, same drill, notebook after each session. My baseline was 1.6 seconds to first shot at five yards from low ready. By week eight I was at 1.28, deviation cut from ±0.22 to ±0.08. That's real feedback.

But I'm going to mark him accepted with the caveat gulfcoast and southpaw already named: he was also running live fire twice a week. I did the same thing for the first five weeks, then isolated dry work only for weeks six through ten. The wobble tightened faster during the concurrent block, then slowed when live fire dropped out. Which tool owned which percentage? Still can't tell. MantisX gave me the feedback loop—I could see the deviation shrink after each dry rep—but that's not the same as proving it was the limiting factor.

Where I'll actually credit MantisX: it caught drift in my reset speed that I wasn't feeling. Took that data and ran five-shot strings from low ready with live fire, and yeah—the inconsistency showed up there too. So the feedback loop is useful for *diagnosing* what to fix in live fire. Not a replacement for it.

SIRT I've tested less because the cost doesn't fit my practice budget. But I did borrow one for two weeks and ran draw-to-first-shot from my AIWB setup. Different animal. Same holster geometry, same concealment, same grip angle I actually carry with. MantisX can't see if I'm clearing the kydex clean or establishing my grip before the press—those are mechanical events that happen before the trigger work starts. SIRT shows you whether the sequence repeats.

If m.delacroix was running par times on low-ready trigger work, MantisX is the right tool. If he moves to draw-from-concealment par times, SIRT becomes worth the notebook entry.
