I'm partial to nice wood on a firearm, looks real good. Now get rid of the "space gun" extension and it'll be beautiful. Joe

The last ditch solution would have been to bore out the thread and install a threaded bushing, it appears that there is sufficient "meat" to accept a thin bushing. Joe B

Too late now, but for future reference, MAPP torch is quite a bit hotter than propane, have to use caution with MAPP on thin or delicate parts. Joe

Search on this forum, lots of info here Joe

Longer but compacts better?? ... got me thinking, count the number of coils on the two springs.... the same, 48 coils on both. Should compact the same you would think. Joe

I'm an old school guy, So, my first "go to" is to convert the metric to imperial to see if there is a common item here in the USA. Sure enough the 1.20 mm wire is = to 3/64 inch ( .047) ... just saying ! Joe

Ask them if you can tape on a length of broom stick to make it 24 or 30 or whatever makes them feel better !!!!!!!!!! Joe B

The initial defect would indicate a poor sweat solder joint between the sight base and barrel. There is a good chance that the sight is not securely attached to the barrel, a hard bump from the side might knock the sight base right off. Also , a good possibility that the brown rust straining will reappear through the new finish. All in all , not a good situation. Joe B

Sometimes you only want one more! Apparently in the Pepoles Republic of New Jersey you can only have six in the mag. I had a request to make one of my custom "NJ Specials" for a fellow there. The extension replaces the OEM extension, allows 6 in the tube. Joe

It sure looks like rust from acid soldering flux not having been properly removed and neutralized.... may even indicate an incomplete soldered joint. Joe B

To facilitate soldering acid flux is used. If the flux is not completely washed away and the residual neutralized rust will result.... like brown rust. Joe B

steel ... 4130 chrome - molly alloy steel Joe

We will wait until others with experience chime in on this one, but something is very unusual here. Just curious , with what were you gripping the tube? Joe B

Looks like FFT's quality work Joe

Someone mentioned the "green stuff" ... be careful with the green loctite, this is the very low viscosity wicking grade designed to be applied after fastener installation... I suspect that it can creep into places that you may not like.... maybe? Joe B
