New member, this is my first post.

I recently bought my wife a 637-2 Airweight and put a Titanium .38/.357 cylinder and titanium center pin in it to reduce weight (not to get .357 ability).

Liked it enough that I did another for myself. For the second 637, I got an extra yoke assembly and a third titanium cylinder and had TK bore it for moonclip and 9mm Parabellum.

TK says the modified cylinder will still fire .38+P and .357 with or without moon clips.
The S&W titanium 120gr minimum bullet weight restriction with .357 or 9mm applies.

I have two questions.
1) Would you guys fire an occasional .357 in the unmodified Titanium cylinders (will the 637-2 frame handle it)?
2) Would you attempt .38 and/or .357 in the rechambered cylinder (would the cylinder handle it)?

Thanks
P.S. TK service is great.
