Now that you know the common problems with the Rock Island 10mm handgun, let’s look at each of these issues and how you can potentially fix them in more detail.

7 Common Kel-Tec P17 Problems: Troubleshooting and Fixes

Problem #1: Failures to Feed

Frequent jams in the Rock Island 10mm can result from lower-quality construction, particularly if parts are made from subpar materials. Issues with the feed ramp geometry or rapid wear can lead to failures to feed. Additionally, hollow-point ammunition may catch on the feed ramp.


  • Contact Armscor regarding construction-related issues with the feed ramp. Replacement parts may be necessary, but long-term issues might persist.
  • Consider using ball ammunition instead of hollow points as a diagnostic measure. Avoid touching the slide during chambering to ensure proper functioning.
  • If failures to feed persist with ball ammunition and no slide interference, consult a gunsmith to rule out various causes, possibly requiring a return to Armscor for a faulty feed ramp.

Problem #2: Failures to Eject

Failures to eject can occur due to issues with the ejector, cases remaining in the chamber, or the rim of the case being ripped off and stuck in the chamber. Causes include poor-quality ammunition, weak recoil springs, or chambers that are slightly too small.


  • If the extractor is the issue, replace it, which is a relatively straightforward task.
  • Avoid using reloaded or low-quality ammunition and opt for higher-quality rounds.
  • If problems persist, contact Armscor, as the chamber may be out of spec.

Problem #3: Recoil Spring Issue

A lightweight 20lbs recoil spring in the Rock Island 10mm can induce irregular lock-up, leading to decreased accuracy.


  • Replace the recoil spring with a stronger one, such as a 23-pound spring, ensuring compatibility with the firearm’s system (source).

Problem #4: Slide Not Locking

Loose gas block screws can reduce the bolt’s stroke, causing some models to fail to lock back slides. This issue may also involve a malfunctioning or rounded-off bolt stop.


  • Test the pistol before purchasing to prevent this issue.
  • If encountered, replace the gas block screw as it wears out to address the problem. Consider adding a stronger buffer spring to prevent recurrence.

Problem #5: Too Heavy for Beginners

Some users may find the Rock Island 10mm relatively heavy compared to other handguns, which can lead to potential imbalance and accuracy challenges.


  • While reducing the gun’s weight is not straightforward, you can consider using lighter-weight ammunition to decrease the gun’s overall weight, making it easier to handle.
  • Practice and familiarity with the firearm can mitigate perceived weight issues as shooters become more accustomed to it.
  • Explore different backstraps and grips to find a more comfortable and balanced grip, further improving control and handling.

Problem #6: Sharp Edges

The thumb safety and other edges on the Rock Island 10mm may be uncomfortably sharp.


  • Soften sharp edges using a fine-grain stone available at gunsmith supply stores. Gently drag the stone down the edges to break the sharpness, or repeat to create a beveled or rounded edge.
  • Exercise caution when working on sliding serrations to avoid accidental damage.
  • While working on the thumb safety and sharp edges, ensure the serration’s flat bottom is protected to prevent unintended surface scratches.

Problem #7: Irregular Lockup

Inconsistent lockup in the Rock Island 10mm can result in misfires and accuracy problems, primarily caused by a worn extractor or an underpowered recoil spring.


  • Replace the extractor with a new one to ensure secure round lockup and prevent irregular lockup. Consider keeping spare extractors, recoil springs, and firing pin springs, especially if you own a Rock Island 10mm or similar 1911 design.
  • Select recoil springs designed for Rock Island 10mm firearms to maintain proper functionality and longevity.
  • Ensure proper lubrication to reduce friction between components and maintain smooth operation.

Problem #8: Jamming Issues

Jamming in the Rock Island 10mm can result from various factors, including poor manufacturing, inadequate maintenance, and the use of cheap ammunition.


  • Address jamming issues by experimenting with different combinations of ammunition, magazines, and extractors.
  • If problems persist, consider contacting the manufacturer, as it may be a design flaw that requires professional attention. Regular maintenance and the use of quality ammunition can also help prevent jamming.

User Reviews for Rock Island 10mm

Not every gun in the RIA 10mm series can make every customer happy. People online have shared both good and bad things about these guns.

For example, one user on the 1911 forum really liked the fiber optic sight on these guns. He thought it was a great feature, especially for the price. He also said the gun is well-made and fits together nicely, which is impressive considering how affordable it is.

But there’s a problem with the grip safety. When you hold the gun firmly and press the grip safely, it sometimes gets stuck in the down position. This is a concern because it could affect how safe and reliable the gun is.

Plus, some users mentioned that the ammo for these guns is more expensive and harder to find. And these issues are on top of the other problems people have talked about.
