Fixation System for the Backstrap of Pistol Grips
The present invention describes a fixation system for the backstrap of pistol grips, preferably micro-compact pistols. The present invention aims to promote better ergonomics for different users of the same pistol. As each person has different hand dimensions, it is not possible to develop a grip geometry that ensures an ideal hold for everyone, thus, the present invention describes a system that allows the interchangeability of backstraps of different sizes, all of which can be fitted to the pistol's grip. To attach the backstrap to the grip, a housing and a tab equipped with at least one through-hole are designed on the grip and a protrusion is arranged on the backstrap, which fits into said housing, and holes for a connecting element to be inserted and held in the holes and the through-hole.

Spearfishing gun with a system for performance and ergonomics enhancement
The invention relates to a speargun equipped with a system for improving performance and ergonomics. The essence of the invention is a system for stopping the contraction of the rubber bands on the lower side of the speargun in roller and inverted roller spearguns. The rubber bands are stopped by a stopping element positioned on the lower side of the speargun. In addition to this stopping element, the stopping of the rubber bands is also facilitated by a connecting element that links the left and right rubber bands, forming a loop that catches onto the stopping element, thereby preventing further contraction of the rubber bands. The stopping element can be implemented in a movable or fixed manner and positioned on the speargun in various ways, allowing different effects to be achieved — stopping the rubber bands at the end of the shot with full power and / or regulating the shot power. The speargun according to the invention allows quick and simple shot power regulation in both directions during the dive, as well as easier loading. Furthermore, by reducing vibrations at the end of the shot, it enhances shooting accuracy.
