This is a superbly sculpted figure, and a nice and unusual subject, beautifully executed.
But at the risk of making myself unpopular again ( the last time was about trumpets ! ) the musket is really too small. This figure is from the late 1500s/early 1600s, I presume from his clothing. There were two sorts of firearms used at that period.
The older was the caliver, bore around 0.5 or 0.6", developed from the earlier arquebus. Calivers were relatively light weapons ,which were used without the musket rest. and normally loaded from a flask and bullet bag. Barrel length varied, but seem mostly to have been around a metre.
The musket, however appeared from the 1560s, and was a much heavier and longer weapon altogether, designed to bring down heavily armoured horsemen at a distance. Bore was around 0.8 " ( later settling at around 0.75", which was standard for the next century or so), and the barrel was at least 48" long .... that's 1.22 metres.
That was a handful to control, and the forked musket rest was invented, essential for steady aim. They were also normally loaded from charge bottles on a bandoleer, as shown on this figure.
So if he's a musketeer,as it appears he is, with a musket rest and a bandoleer, he needs a larger weapon with a longer barrel.
Sorry to be a pedant...
