They are Walther clones in the respect that they look very similar, but their innards function quite differently. Impressions These are posts from DejaNews and have been edited a bit.

In preparation for this I had purchased several boxes of .380 ammo to try. The magazines worked OK with FMJ cartridges. When I measured the Cartridge Overall Length on them the FMJ rang up at .971 inch and the Hornady XTP at .981 inch. The XTP bullet is also a truncated cone shape which may contribute. The stock is longer to hold the extra round.
