I would totally agree with the above response.
TMs mostly come with plastic slides. They will work for some time but will crack. Get aftermarket metal one.
Watch the guide rod guide, or housing. Its the part that slips into the slide and captures the guide rod. The flange breaks off, and will not capture the guide rod.
The rear sight for height screw will like to back out. Locktight that bad boy, and watch the screw for windage. They break off , or back out.
I have over 30,000 bbs through mine, and have replaced the following:
Guide rod guide
Magazine release
Both adjustment screws for rear sight
Slide
Mainspring
Loading Valve
Piston head
Valves in mags
Inner barrel.
The last 6, I replaced for performance, and or reliability.
The Caspians in the wide body series are all metal and also well made. Those mags work in the TMs. I can get all parts for that series here in the states. They are an excellent value, and quite well made.
Evike sells them pretty cheaply.
Oh, BTW..Sweet TMs you have there good sir.
