Frequently Asked Questions

What tools are needed to disassemble a Ruger LCR?

To disassemble a Ruger LCR, you'll need vice grips, a handle with a number 10 Torx bit, a 1/16 punch, and potentially a standard screwdriver for older models. An ejector support tool is highly recommended for cylinder disassembly, though spent casings can be used as an alternative.

How do you safely separate the Ruger LCR frame halves?

When separating the Ruger LCR frame halves, it's crucial to hold them together to manage the hammer spring tension. Slightly pulling the trigger helps lower the cylinder latch, preventing it from getting caught and bending the spring as you carefully pull the halves apart.

What is unique about the Ruger LCR ejector rod?

The ejector rod on the Ruger LCR features a left-hand thread, meaning you must turn it clockwise to loosen it. This design requires careful handling, especially when supporting the ejector to prevent damage during removal.

Why is it important to re-thread the ejector rod immediately after removal?

The thread lock on the Ruger LCR ejector rod is time and pressure sensitive. Re-threading it immediately after removal preserves its locking ability. If left unthreaded for over five minutes, it can lose effectiveness, causing the rod to unscrew during use and potentially tie up the firearm.
