Probably going to go with the G17 ( always nice to have parts )
Would propane be bad for the gun or would it make just a small difference compared to duster?

TM are designed for duster. I run all my TMS on propane with no problem so far...

So... if things breaks, it's an excuse to buy new parts :D

Okay, thanks

Some people have had cracked TM Glock slides with propane, but replacement metal slides and springs sets are easily available and run between 100-150$. Because of the square shape, the Glock slide is not as impact resistant as the other TM plastic slides. With that said, they will usually last a while, its rare that they crack in the first few games. Some people have been using them with plastic slides for years.

So if the slide were to break it would be relatively easy to replace?

Very simple.

It just costs you 100-200 USD depending on the brand. I ran my old old TM M&P9 last winter season on propane, had no problems. Sold it to a good friend and he dropped 800 bucks immediately upgrading it to tits.

yes, but when you get a metal slide, its a good idea to get a metal guide+ spring as well. You can also epoxy the slide if it starts to crack for whatever reason like if your short on cash and a game is coming up soon.

The TM's already come with a metal guide and spring, which is an upgrade on the polymer unit on the actual Glock. Upgrades are nice, but in the end you just need a 150% spring on a metal slide.

So, i've sorta decided what im going to get ( over time )

TM G17
PGC Metal Slide/Barrel Set Marui G17 BK
Guarder 150% Enhanced Recoil/Hammer Spring
GUARDER ORIGINAL FRAME FOR MARUI G17

Would these upgrades be the best for using GG? Mainly looking to make it last long on GG.

Yeah you look good on your plan in my opinion but I don't think you will need the frame for a while. In my opinion use it until something breaks, replace and use it again.

If I think he's getting the frame from where he's getting it from... I.E. A Canadian retailer... it may be worth getting it now as resupply on that frame is erratic to say the least.

one thing I have noticed on my TM G17 is that the slide will pop off the back sometimes on propane. I've started to ensure I only use half cans of gas on it and not fill it for too long. Strange though that it's never happened on my G18c...

How well would the TM G17 perform in 1-5°C, and if it doesn't work would a Co2 pistol perform better?

KJW MAGS SUCK, constant leaks and repairs...other then that the pistols works fine, I have KWA Pistols USP/M 9/M 93X...no magazine or maintenance problems

Currently loving my Kwa M93r. It feels like it can take a beating, but ill still baby it though.
