Hi All,
Just working on my project Pistol a TM G18c AEP. I was looking for a threaded barrel/slide and there isn't much choice. I however did find the new Novritsch SSE18 slide will fit. If anyone wants to do the same, it does require some slight modifications. The end of the plastic barrel needs cutting down and the internal top cover need chamfering to fit the internal profile of the slide. (Optionally you could order the SSE18 top cover, which looks like it will fit). Its a snug fit but, locks together well. The metal slide is actually a few grams lighter that the plastic TM one, and I prefer the sights.
