TK Custom 9mm conversion

[brassburnz]

Before you have the cylinder machined for the moon clips, have your spare cylinder fitted to your gun.

As old as your 686 is, it is likely that the timing will be a bit off. Tell him you still want it to work with your original cylinder so that he does the adjustments on the star and not the hand

Good advice. My gun is a 686 no dash and the cylinder I bought is for a 686-5. The variants don't state any changes to the cylinder, but there was a design change to the hand in the 686-1.

A cylinder from a 686 no dash would have been ideal, but hopefully the two cylinders are similar enough to not require major work. Hopefully any changes can be made to the cylinder and not the gun.

Isn't the whole point of doing 9mm in an N frame being able to fit 9 rounds in the cylinder? If you're just leaving it at 6 rounds, why 9mm?

I just bought a 627, it only holds 8 rounds. Did the guy at the gun store gyp me?

Damn! I must have gotten screwed on my 929 too..

The 627 PC thread got me thinking about the TK Custom 9mm coversions.

$300 to rechamber the cylinder

$50 for recessed cylinder

$80 for 10, 9mm moonclips

Depending upon which gun I choose to convert, it will be either $380 or $430 based on today's price list.

NOTE:

Our work on cylinders rechambered to 9mm are LIMITED to our customer's using standard 9mm ammo or low pressure reloads, which are 34,000 - 35,000 psi chamber pressure or less. Same chamber pressures apply to firing of .38 SPL & .357 Mag. Examples of FACTORY Brands are: Winchester, Federal & Remington.

Absolutley NO 9mm Nato, 9mm +P or 9mm +P+, all which are far beyond the 34,000 - 35,000 psi chamber pressure our conversion is intended for. Usually 38,500 psi, which WILL Stick!

If you try to use these high pressure ammo, you will experience cases sticking in all chambers.

We cannot warranty our work, if you disregard our warning/notice on high pressure ammo.

When rechambered to 9mm the cylinder will still shoot NON-HIGH Pressure ammo, 38 SPL or 357 Mag with or without the proper moonclip.

Reloaded range brass, with the unsupported barrel chamber bulge, will not resize properly and results in inferior ammo for use in this conversion!

I saw the disclaimer about high pressure rounds. I don't plan on shooting any 9mm NATO or other hot rounds. I've seen what happens when people shoot 9mm Major in stock Glocks with unsupported barrels. Not pretty.

TK Custom is talking about brass fired from Glocks in reference to range brass with a case bulge. I plan on shooting factory 9mm in the revolver and only reloading revolver fired brass.

I don't usually shoot hot .357's out of an L frame, but that's another reason why I want to keep the original cylinder as is. You never know.
