SVI Infinity 10,000 Round Report

| June 3, 2011 | 2 Comments

The Gun:

SVI 2011, all steel, 6″ bull barrel, .45 ACP. You can check out my initial impressions and 5000 round report for more details.

Ammo:

200 Federal HST 230gr +P
9800 Reloads, 4.7gr Bullseye under 230gr Missouri Bullet LRN

Maintenance:

Field stripped and cleaned after every range session, typically 200-500 rounds. Detail strip and clean every 2000 rounds. Recoil and firing pin springs replaced every 3000 rounds. Fire control parts and trigger bar lubed with FP-10, slide, frame and barrel lubed with low viscosity Slide Glide.

Malfunctions:

None.

Accuracy:

Better than I am. I was hoping to have some nice target pictures to illustrate my point, but I did pretty awful at the range today.


The bulls are 2″ across, I shot 50 rounds per bull at 50 feet, a grand total of 400 rounds. I wasn’t really keeping track of my rate of fire, but the entire session took a little less than 40 minutes total, including time to load mags, etc. On better days, I can easily keep 90% or so of my shots in the 2″ bull.

Modifications:

Every gun SVI makes is a full custom build, so there’s not really much need for improvement. The gun has been pressed into the role of daily carry the last several months, so I rounded off the edges of the rear sight after it tore one of my shirts:

Wear:

First, a bit of an exploded view. The trigger and mag catch are still in the frame, and the frame is still attached to my grip because I can’t for the life of me unscrew the mag catch button or the screws the hold the grip to frame at the front of the trigger guard. They’re very small allen heads, and my wrenches just keep slipping. Also, 10 gun nerd points if you can name the part that I accidentally left out of the picture:

The two pictures at the beginning of the thread were taken today, with 10,000 rounds through the gun, and illustrate just how well the Infinicoat finish stands up to wear. It still looks almost new, even with daily carry in a kydex holster. Once to take it apart, however, you can tell the gun has actually been shot.

Frame:

Slide:

Here’s a closeup of the slide locking lugs. As you can see, even symmetrical wear:

The barrel locking lugs also have symmetrical wear:

As you’d expect with a round count so low, most of it lead, the rifling is more or less pristine:

The finish has really worn off the breech face, but the metal itself is pristine. No pitting or peening, no deformation of the firing pin hole, either:

The ejector still looks brand new:

And here are a few shots of the extractor, still in very good shape:

The only unusual wear I can find on the gun is on the firing pin stop of all places. The firing pin has peened in a little circle on its internal face. Not really serious, but I find it kind of unusual, given the stop is steel barstock and the firing pin is titanium:

General Impressions:

This is a phenomenal pistol. The part quality, machining quality, and fitting are all superior. Perhaps the best illustration of this was something I did just out of curiosity while I was taking pictures for this post. I put the slide on the frame and ran it back and forth with no lube, and it was infinitely smoother than my 15,500 round count Les Baer with proper lube. The smoothness of operation is really what’s most impressive about this gun. Right out of the box it was silky smooth, better than any other gun I’ve ever handled. What surprises me however, is that it hasn’t changed. Every other gun I’ve ever had experience with, including plastic guns, smooth up over the first thousand rounds or so. My Baer took about 5000 rounds before it stopped getting smoother every time I shot it. This is a testament both the precision of SVIs machining and the durability of materials, parts, and construction. Shooting the gun remains an absolute pleasure. The trigger is phenomenal, and the gun practically shoots itself. You really have to try to shoot poorly with it. The one downside I’d say the gun has is the magazines. They’re top quality (and boy do you have to pay for it) but the 2011 was designed as a competition platform, and SVI is a heavily competition-oriented company. If you’re not aware, most USPSA/IPSC competitors disable their slide stop’s ability to lock back on an empty mag to eliminate the chance of accidental lockback with rounds still in the magazine. As such, the SVI followers were designed with capacity as the primary priority and lockback as a distant second. I can’t get the mags the lock back the slide reliably. I’ve been in communication with the company (their customer service is the best I’ve ever dealt with, in any industry) and they’ve given me a few ideas on spring modifications that will aid in lockback, and I’m currently experimenting to find a solution. If that doesn’t work out, SVI is developing a more lockback-friendly follower design, and they’re promised to send me ones for all my mags when they’re complete.

    I don’t see the plungers or plunger spring…

    STI mags will work in your SVI and are a bit cheaper. They should also give you reliable lock back.
