I bought a used Taurus revolver that the previous owner apparently modified and it has a barrel cylinder gap around .0016 (sixteen thousandths).  would it be a major undertaking to have a gunsmith remove the barrel and screw it in further to make the gap more reasonable?  the gun shoots fine, but has one hell of a fireball from the gap....in 38spcl.

Or should I just junk it?  If the job was $100 or so I wouldn't mind having it fixed, but I don't think the pistol would be worth $200 even after it was fixed, so if the job was $200 it probably wouldn't be cost effective.  Cosmetically, the pistol looks really good to nearly new.

16 thousandths of an inch is 0.016 inches.

0.0016 inches is excellent gap, 16 ten thousandths, probably too tight for anything but a target pistol.

Cost to adjust excess gap is surely greater than $100.  Remove the barrel, set back the shoulder 1 turn and hopefully thread to the shoulder, install the barrel to measure the material to remove to set the gap, remove the barrel and machine, recut the cone, install and check the work.  Tweak if necessary.

The competent gunsmith's labor is worth $100 per hour or very close.

Keep your powder dry, and watch your back trail.

Sixteen thousandths is written as .016, if yours feeler gauges at .0016 that is 1.6 thousandths.

Whichever is correct would determine action needed.

Shoot it. If it spits lead, send it in under warranty. No manufacturer is going to fix something due to a dimensional problem. They will for bad accuracy, spitting lead, etc…..maybe.

I shot it and got a hell of a flash out of the barrel cylinder gap, but I didn't have anything set up to the sides to see if it was spitting lead.  I'll have to get it out again and check the gap with my feeler gauges.
