Brazos Custom

Check the overtravel. Having too much overtravel will cause this.

Sorry, no that is not available. We will offer slide to frame fits with our frame and slide. I will have them on the website in a few days.

It turned out great. I like that finish.

N105 if you can get it is my favorite, 3N38 is my second choice. Also try 9 or 10 lb recoil spring.

Pretty close. Still a few variables depending on burn rate, barrel, etc.,but pretty close.

To compare you would want the case volume when the bullet is seated to be the same, not the same OAL. Shorter bullet would need to be seated further in. Pressure peaks in the first couple tenths of an inch. Small changes in the amount of case volume can mean big pressure spikes. That's why people worry about setback. Gas volume and pressure both work the comp. High pressure can work as well as lots of gas but more wear and tear on the gun.

Might want to read the directions that come with the grip on how to install the magwell.

I have seen plenty of STI with TG prefix. I have also seen quite a few with a pocketted serial number. Most likely they messed up the serial number and had to re-do. They machine the old number off and put the proper one on.

Those are not STI mags. STI gen 1 mags have 2 ribs running down them on each side. 38 has deep ribs on both sides. 40 has deep ribs on one side and shallow on the other. The mags shown look like they might be older SV mags.

O.D. diameter of the barrel should be 0.695-0.696. The barrel has to be undersize enough to let the barrel cam up in the slide during lockup. Blueprint spec on the slide bore I.D. is 0.699 +0.003. 0.699-0.700 slide I.D. works well with 0.695-0.696 barrel O.D. to allow full lockup with no play.

Chamfer the bottom edge of the barrel ramp a little and roll the right edge a little and then take a little off the high spot on the magazine. I like having the ramp as far to thee rear as possible so that the nose of the bullet contacts the ramp as soon as possible.

the Harvey Tool is measured to the radius on the dovetail and will cut oversize. I do not recommend them.
