I have a 24000KT with an LW barrel & a TKO. The 2400KT only offers the long steel breech as it is a carbine. The 2300 offers the long & short breech if you just want a pistol and shorter/lighter breech.The TKO is a great suppresser. I have a number of them and have no complaints.Best order tonight as sales in the Custom Shop don't happen very often.Go for it...….
