Duration: 12:10

This video explores the KelTec P17 .22LR pistol, focusing on its potential as a budget-friendly firearm. The presenter details the challenges of adding a red dot sight to the lightweight pistol due to its blowback operation, which can be exacerbated by the added weight. The video demonstrates that a suppressor can mitigate these issues, and a lighter, fiber-optic red dot sight is recommended for unsuppressed use.

Quick Summary

Adding a red dot sight to the KelTec P17 .22LR pistol can cause cycling issues due to its lightweight blowback operation. To ensure reliable function, either use a suppressor to increase back pressure or opt for an extremely lightweight red dot sight, like a fiber-optic model, to avoid disrupting the firearm's action.

Frequently Asked Questions

What are the main challenges of adding a red dot sight to a KelTec P17 pistol?

The primary challenge is the added weight of the red dot sight, which can disrupt the P17's lightweight blowback operation. This often leads to cycling issues like failure to eject and failure to feed, especially when the pistol is not suppressed.

How can the cycling issues with a red dot on the KelTec P17 be resolved?

Two main solutions exist: either always shoot the P17 with a suppressor to provide necessary back pressure, or use an extremely lightweight red dot sight, such as a fiber-optic model, that doesn't significantly alter the firearm's cycling dynamics.

What type of red dot sight is recommended for the KelTec P17 when not using a suppressor?

For unsuppressed use, a very lightweight red dot sight is crucial. The video suggests a fiber-optic optic, like the Ruger Red Dot, which is light enough not to impede the P17's blowback action and allow for reliable cycling.

Are there factory solutions for mounting a red dot on the KelTec P17?

Yes, KelTec offers an optional complete upper receiver for the P17 that comes with a built-in system for mounting red dot sights. However, this upgrade can be quite expensive, potentially costing as much as the original pistol.
