I’m considering a conversion to 10mm for my Glock 21 and looking for some advice.

What to Consider for the Conversion?

When converting a Glock 21 to 10mm, I’ve heard that the most critical component is the barrel. Here are some key things I’m curious about:

  • Conversion Barrels: What are the most recommended brands? Are there specific models that work better?
  • Compatibility: Will I need to change out my magazines or any other components?
  • Slide and Extractor: Are there any modifications necessary for the slide or extractor to handle the increased pressure?

Reliability Concerns

I’ve read mixed reviews about conversions, especially regarding reliability and function. I’d like to hear about:

  • Experience with Conversions: For those who have made this change, how has it affected performance? Any issues with jams or misfeeds?
  • Versatility: How well does the conversion handle both .45 ACP and 10mm? Is it easy to switch back and forth?

Recommendations Needed

If anyone has recommendations on the best conversion options available or personal experiences to share, I would greatly appreciate it!

Looking forward to hearing your insights and personal stories about the best Glock 21 10mm conversion techniques!

Basic tools worked fine for me. A torque wrench was handy, but not mandatory. Just take your time, and you’ll be golden!

Has anyone experienced any major issues with feeding or ejection with these conversion kits? I’ve heard mixed reviews.

I’ve had a few jams with my conversion, but it seems like a break-in issue. After a couple of hundred rounds, it got smoother. Just keep your chamber clean!

Interesting point, @cobrien! I’ve heard that too, but I wonder if certain brands are more prone to issues than others? Anyone have a perfect experience?

I tried a few and didn’t have feeding problems with the 10mmK. It has been significantly reliable for me. I think it depends on the individual gun as well.

So, it sounds like finding the right kit is key! Any tips on how to choose a reputable brand? Such a minefield out there.

I generally stick to brands with solid reviews in forums like this. GlockTalk and others usually help me avoid any junk kits! Just do your research.

It’s like dating—don’t rush it! Make sure you do your homework and choose wisely! Otherwise, you might end up with a total lemon.

I’ve done a 10mm conversion on my Glock 21, and the performance is noticeably improved. The recoil is sharp, but manageable. I’ve found I’m hitting my targets more accurately at longer distances.

That’s interesting! I’ve always heard 10mm has quite a kick. How do you find the recoil compared to other calibers?

16

I’ve had a different experience. My Glock 21 10mm conversion had a lot of muzzle flip, which threw me off my aim. It took extra practice to get my precision back.

17

That’s unfortunate! Did you try any specific techniques or accessories to help manage the recoil?

18

I found that a heavier grip made a difference for me when converting to 10mm. The added weight really helped stabilize my shots.

19

I’m planning to do the conversion soon. Is there anything in particular I should look for in a conversion kit to improve accuracy?

A good barrel is key! I recommend going with a reputable brand. It can enhance your accuracy drastically.
