Same with the WE - based off the TM design, but with tolerances different enough that they're nearly their own class of gun. Some have also come through my possession with extremely weak springs. Nice case though.

Some Guarder frames are already iffy with Tokyo Marui Glock 17s, let alone a Bell. WE/HK3P frames require a Safety Tag delete to function correctly. You may have to sand and adjust accordingly. All Glock 17 frames have a fatal defect in the front screw post - I would estimate this flaw will show itself earlier, rather than later, in the Bell Glock 17. A Tokyo Marui Glock 17 was my first build - I would argue that having invested in a gun where the tolerances were good enough that most parts dropped in, made it a much safer project gun, compared to a TM/HK3P/KJW Glock 19 I put together, where everything didn't fit and sanding made the difference between too tight, perfect fit, and ruined parts. But you've made your choice.

As per your desired parts:

- Don't bother with a separate extractor. I have one, and it does nothing. At that price point? Not worth the investment of probably ruining a new slide.

- If your gun is firing well enough, leave the magazine valve alone. I haven't seen an upgrade valve that was worth my money. For the record, I use stock WE magazines in a TM.

- Hammer: Hammers are finicky. Very finicky. Someone else will have to chime in - even the hammers for TM Glocks need adjustment and filing, in my experience (Again, stock one here, several thousand rounds.) See if your hammer spring experiences light strikes, then upgrade if you have to. These guns can fire CO2 so I doubt it.

- Night sights: Nice to have ones are Guarder steel, if you can find them.

My honest advice? Use the gun to see how a GBB works, and ride it into the ground. You'll have enough experience with them to pursue a rewarding project then. Otherwise you're setting yourself for a lot of heartbreak - and I've been there, lining up to buy a TM after my cheap KSC project failed.

Thank you sir for taking the time to make this post. I greatly appreciate it!
