And for those preferring something a little more mainstream the RWS 45 ticks a box. I appreciate its basic uncluttered lines, especially in the hunting field where I use them exclusively. And in respect of the 45's bland stock this has actually grown on me over the years. They are both German guns and get my vote, but the 45 edges it for me. Like a lot of guns the Sport is a mixture of high quality German engineering and "what the hell were they thinking of design" such as plastic rear sight, feeble and temperamental safety slide, and basic trigger design and adjustability. Whereas the Sport can get there but requires more refinement of technique and hold. I find the 45 is easier to achieve a good level of accuracy with over the Sport. But the 45 is a more robust gun, its trigger superior to the sport despite it being a little shapeless and is certainly stronger (says he who clumsily snapped a cast Sport trigger). Aesthetically the Sport is easier on the eye alright and is very pointable as a hunter being lightweight and easy to manoeuvre within woodland on grey squirrels for example. Owning a few Sports and 45s I would say that build quality and finish is pretty much on par with both marques.

There is a small stop clip on the screw which should prevent the engagement being set dangerously shallow. Turning the adjuster screw clockwise will reduce the depth of engagement of the sears and slightly increase the trigger pull needed for release. Same can apply if the vertical spring breaks since the horizontal spring will hold the blade in the triggered position. May be worth mentioning that if non standard springs are used it can result in failure to cock. This balance of geometry and spring forces is common in trigger devices. It can be seen that the relative strength of the two springs is critical since the small horizontal spring is trying to force the blade to the triggered position and only prevented from doing so by the larger vertical spring pushing in the opposite direction via the inter mediate sear.

On the left the mechanism is uncocked, or triggered, by the blade turning anti clockwise which turns the intermediate sear clockwise to release the main sear.

On the right the mechanism is cocked, normally by the piston latch rod, with with the intermediate sear preventing the main sear turning to release the latch rod. The larger spring acts, between the safety slide and the intermediate sear, to turn the intermediate sear anti clockwise. The smaller spring acts, between the front face of the trigger blade and the lower edge of the main sear, to turn the main sear clockwise. The layouts above shows the parts in their relative positions. The rear pin pivots the intermediate sear. The front pin pivots the trigger blade and main sear. The pins usually push out with little effort taking care that the springs don’t fly away. The trigger assembly consists of a trigger blade with adjustment screw, safety slide, main sear, intermediate sear, and two springs, all located and fixed in position by two solid pins. The trigger unit with fixed spring guide can now be safely removed for inspection/service.

The pre load now is almost completely removed at 100 mm with this standard spring from T W Chambers. The slide can be taped in place or simply held until fully exposed then removed. A spacer is useful to avoid crushing the safety tab.Īs the block travels out of the main cylinder the safety slide becomes exposed and is forced away from the block by the intermediate sear spring.

In original trim the mainspring pre load is around 100 mm so before unscrewing the fixing lug it is advisable to use some form of restraining clamp to control the force and reduce the risk of damaging the quite flimsy threads. The block is located and fixed in place by a threaded lug which also forms the rear stock locating/fixing dowel. The trigger unit, or block, is fully enclosed in the main cylinder and must be withdrawn to enable dismantling. Put this together and would appreciate some snagging.
