Another month, another Staccato post. I can’t help it—I’ve been shooting Staccatos almost exclusively for the past year and a half. This time, you’re spared my ramblings about the XL. Instead, I’m focusing on an update review for the Staccato C2 and its mounted Holosun 507COMP. This post celebrates a milestone only a handful of my pistols—countable on one hand—have reached: 5,000 rounds. The C2 is the fourth to hit this mark.

The Significance of 5,000 Rounds

For most, 5,000 rounds is a big deal. Some never shoot that many in a lifetime. Others might hit that in a year or even a few months. A rare few burn through that in weeks. Regardless, reaching this number takes resources and effort. In my mind, it’s a solid benchmark for judging a gun’s durability. If those rounds are fired in a condensed period—say, a year or two—it’s a safe bet the shooter knows the firearm inside and out. For my C2 and its accessories, it took about 13 months.

State of the Staccato C2

The 5,000-round mark is my durability milestone, but reliability comes first. If a gun doesn’t go bang when you need it, durability is irrelevant. I’m happy to report in this review that the Staccato C2 has been flawless since a warranty repair before the 500-round (reliability) milestone. This is critical since the C2 is my everyday carry (EDC) defensive pistol.

Durability, while related, is distinct—it’s about withstanding wear over time. The reliability milestone (500 rounds) typically takes me a few weeks, maybe a month, for a pistol intended for defensive or competitive use. The durability milestone (5,000 rounds) requires ten times the ammo and nearly a year—an order of magnitude more use and time.

Beyond carrying it on my hip, I’ve put the C2 through its paces. Since the last milestone, I’ve competed with it at least a dozen times and used it in these events and classes:

• KR Training Top 10 Drills Level 2
• KR Training Advanced Handgun (Again)
• Rangemaster Professional Pistolcraft Instructor Development Course
• Gabe White’s Pistol Shooting Solutions (Yet Again)
• KR Training Top 10 Drills (Yet Again)
• TacCon 2025

That’s a lot of live fire, dry fire, and holster work in environments from humid to dusty, cold to hot. The C2 keeps running. Despite claims that 2011s need constant TLC, I’ve done minimal maintenance: oil before each use and a wipe-down field strip every 500–1,000 rounds. External wear is nearly nonexistent. Internal wear, noticeable since the 1,000-round mark, is shinier but not excessive. It’s still running with original pins and springs. I’d call the C2 durable.

While I expect another 5,000 rounds from it, mechanical devices eventually fail. I suspect the recoil spring might be the first to go, or perhaps an extractor. As my EDC and life-saving tool, this milestone prompts me to consider a second C2. Once proven reliable, it could take over EDC duties, letting this one handle the wear of training and competition.

A second C2? Expensive, but likely. Not immediately, but soon. The C2 is arguably my favorite Staccato. That might surprise those who know I own a P and an XL. The P’s a bit too big for carry, and the XL dominates my competition time. But the C2’s recoil profile—snappier yet quick to reset—feels great. With four two-day classes on my calendar this year, the C2 could near 10,000 rounds by Christmas. I’d love to carry a fresh, low-round-count C2 by then.

If I get another, it’ll be similar but not identical. I’ll stick with the compact grip for concealed carry. The X-series serrations stay—they look sharp and make slide manipulations smoother. I’ll add a Dawson Precision magazine well, as I did on this C2, for faster, consistent reloads. A DLC-finished barrel, like my other Staccatos, helps track wear patterns. Instead of another 507COMP, I’m eyeing a Trijicon RMR HD—partly because I’ve been wanting to try one.

Overall, I’m thrilled with the C2 and see our partnership lasting indefinitely.

State of the Holosun 507COMP

I was once a “Trijicon or nothing” guy, swayed by their gold-standard reputation. But mentors kept calling Holosun a close second at half the price. That wore me down, and I started trying Holosuns to save a buck. The 507COMP won me over after handling 2,000+ rounds on my Shadow 2. When I ordered the C2, I wanted a big-window optic and saw no reason to pay double for a Trijicon SRO. As of this review, the Holosun 507COMP has endured all 5,000+ rounds on the Staccato C2 without major issues. Between the C2, XL, and Shadow 2, I’d say the 507COMP is reliable.

It’s also durable. I’ve used it as leverage for one-handed malfunction drills, and it’s held up—no looseness, no cracks, minimal wear. The lens gets dirty from ejection port carbon, but that’s it. I replaced the CR1632 battery once; it didn’t hit the advertised 50,000-hour runtime. Maybe it was an old factory battery, or maybe it’s because I run max brightness and occasionally forget to turn it off (a rare activity since I wear the C2 almost constantly). The new battery should last until my birthday in November—a good day to swap batteries in all my optics to avoid a dead dot when I need it most.

On bright sunny days, I sometimes wish the dot were brighter. My other 507COMPs don’t have this issue, likely because I run them occluded, which acts like a sunshade. This has me considering the Trijicon RMR HD for the next C2. I’m also curious if newer “Ronin” 507COMPs, optimized for concealed carry and duty, are brighter than the competition-focused originals.

For now, the 507COMP is my favorite optic, and I have no qualms using it for defensive purposes—otherwise, it wouldn’t be on my EDC C2.

State of Other Accessories

Two accessories have joined the C2 for all 5,000 rounds: MBX Defender magazines and a JM Custom Kydex IWB 3 holster.

I replaced springs and followers in MBX 23-round competition mags for my P (now used with the XL) before hitting 5,000 rounds, so I was skeptical about the Defender mags. Chosen to boost the C2’s capacity from 16 to 18 rounds without altering dimensions, they’ve been flawless across all units, including those for heavy practice. My usual magazine management ensures none fail at critical moments, and the Defenders have proven durable.

The JMCK holster has had zero issues over the past year-plus. No surprise to those familiar with JM Custom Kydex’s reputation for quality and durability. I’m mentioning it for those who aren’t—consider this a nod to a solid product.

What’s Next

A second C2 is a strong possibility. It’s not certain—saving up takes time and discipline, and I’m as easily tempted by shiny new guns as a cat is by a laser pointer. To those asking about a Staccato HD: it’s a soft no. They’re cool, but not worth the price for me. I wouldn’t say no to Staccato sending one for testing, though. An XC? Maybe—a strong maybe leaning toward yes. Still, another C2 is most likely.

You’ll definitely hear more about this C2. I’m competing with it tomorrow and will keep using it until the XL returns from warranty repair. Two two-day classes this month will see the C2 chew through at least two cases of 9mm. That won’t hit the next milestone, but it’s a solid start toward 10,000 rounds by Christmas, making a follow-up Staccato C2 and Holosun 507COMP review likely.

In the meantime, let’s compare notes. What milestones have you hit with your EDC, optics, magazines, and holsters?
